Description

Technical Field

[0001] The present invention relates to a cloud-based simulation method and a cloud-based simulation webpage for industrial software, and belongs to the technical field of cloud computing simulation. Background Art

[0002] In the field of modern industrial design and engineering analysis, the application of industrial software has become an indispensable part. For example, Ansys, as a leading software widely recognized in the industry, helps engineers predict performance and optimize design in the early stages of product development with its powerful simulation capabilities. However, despite the significant technical advantages of industrial software, the high software licensing fees and the need for high-performance computing resources limit its application in a wider user group. Especially for small and medium-sized enterprises and educational institutions, the initial economic investment and subsequent operation and maintenance costs have become the main obstacles for them to use industrial software.

[0003] With the rapid development of cloud computing technology, it has become feasible and necessary to provide an industrial simulation software service based on a cloud platform. The core advantages of cloud computing are its elastic resource allocation, pay-as-you-go, and high scalability, which provide an ideal solution to the cost and resource problems encountered in the use of traditional industrial software. By deploying industrial software on a cloud platform, users can access simulation services anytime and anywhere, no longer restricted by local hardware configuration, and greatly reduce the threshold for using the software and the total cost of ownership.

[0004] Furthermore, the Chinese patent application (CN112187955A) proposes a method for providing casting mold modeling and simulation cloud computing services based on a SaaS platform, including: receiving a registration request and a login request from a user to log in to the SaaS platform, and allowing the user to log in to the SaaS platform after the review is passed; after the user successfully logs in to the SaaS platform, the SaaS platform receives the three-dimensional geometric model and process parameters submitted by the user, and then provides SaaS services to the user; after receiving the calculation task submitted by the user, the SaaS platform uploads the three-dimensional geometric model and calculation parameter configuration information to the supercomputing site, calls the supercomputing API to submit the calculation task, obtains the calculation status information in real time, and transmits it back to the user layer for the user to view; the supercomputing API calls the calculation core program to complete the calculation task, including the supercomputing API calling the grid division, flow field calculation, and temperature field calculation core programs to calculate the flow field and temperature field corresponding to the mold design scheme submitted by the user, and generates calculation results and calculation status information in real time during the calculation process.

[0005] When users use the above-mentioned simulation cloud service solution, they first submit the 3D geometric model and process parameters to the SaaS platform. The SaaS platform then uploads the 3D geometric model and calculation parameter configuration information to the supercomputing site for calculation. Although this allows the solution process to be cloud-based and reduces user costs, the entire simulation process lacks effective interaction, which requires users to set all process parameters at one time and cannot set corresponding parameters for local features of the 3D geometric model and different end faces separately, affecting the flexibility and accuracy of cloud-based simulation, resulting in a poor user experience and is not conducive to the promotion and use of cloud-based simulation.

[0006] The information disclosed in this Background Art is only for understanding the background of the inventive concept and therefore it may include information that does not constitute the prior art. Summary of the invention

[0008] In response to the above problem or one of the above problems, the second object of the present invention is to provide a cloud-based simulation web page for industrial software. By setting a Web pre-processing module, a motion capture module, a software pre-processing module, a software post-processing module and a Web post-processing module, it is convenient to interact with users and obtain user operation information, thereby significantly improving the efficiency and effect of simulation processing, enabling users to make decisions more accurately and quickly, and optimize design and performance.

[0054] In this way, the present invention further simplifies the complexity of simulation pre-processing, making the engineering simulation process more efficient and user-friendly.

[0055] After the pre-processing operation is completed, the software pre-processing model is used to generate the input file required by the industrial software solver. The file is in .dat format and is an input file under the industrial software ecosystem. It can be an input file for solving modules such as statics and heat transfer. Then, by connecting to supercomputing resources, the present invention can efficiently submit the solution task to the supercomputing center to ensure fast and efficient calculation execution.

[0155] After the calculation is completed, the present invention will use the post-processing function of Ansys to convert the calculation results into a standard, visual file format. Currently, it is through an open source library of Ansys, ansys-mapdl-reader, to convert the above result files (such as files in .rst.rth format) into files in .vtk format. This format is a more common post-processing file format in the industry and has good ecological support. Then, the present invention parses the general visualization file. Specifically, the parsing process is to parse and render the results to the Web end for files in vtk format using the vtkjs open source library, and finally realize the intuitive display of the results on the Web end, providing users with a seamless, efficient, and easy-to-operate simulation process. The final effect is that the Web end can display a three-dimensional visual simulation object that the user can freely rotate, and it carries information about the simulation results, such as the stress / displacement results on the model.

[0156] like Figure 3 As shown, a specific embodiment of the Web pre-processing of the present invention is:

[0157] In this embodiment, a highly innovative pre-processing process is described in detail. The present invention provides a powerful Web-side interface that enables users to directly process various common geometry file formats, such as IGES, STEP, BREP, and XAO, which are all open source geometry file formats. The present invention uses some open source libraries, such as OpenRadioss, to convert these geometry files of different formats into a unified data structure for subsequent processing. These formats are widely used in computer-aided design and simulation software. Through this interface, users can perform a series of pre-processing operations, including but not limited to:

[0158] Rendering geometric models: Displaying the model in an intuitive way so that users can clearly observe the details of the model. That is, through Canvas and WebGL technology, the unified geometric file data structure of the present invention is displayed on the Web end.

[0159] Zoom and rotate the view: flexibly adjust the model's view to examine and analyze geometric shapes from different angles. That is, through some mouse interaction events, change the camera's view / position in WebGL to achieve the effect of model zooming and rotating. For example, holding down the left mouse button and dragging can change the camera's view position, thereby changing the rendered model's view. For example, holding down the right mouse button and dragging can change the camera's placement, thereby changing the rendered model's position.

[0160] Select specific geometry or faces: Accurately select specific parts of the model for further operation or analysis. Some interactive events are implemented, such as left-clicking a geometry / face of a model, which will highlight the geometry / face and prompt the user that the geometry / face is selected.

[0161] The integration of these functions provides simulation engineers with a powerful toolset, enabling them to efficiently complete the pre-processing of the model on the Web. After completing these operations, the present invention will split and clean the operations. The splitting and cleaning specifically include the following processes, such as the merging of repeated operations. For example, if the user repeatedly clicks on the geometric surface to set the force, it will be merged into one setting at this stage; such as the cleaning of invalid operations, such as repeatedly setting the material for a geometric body, in this stage, all materials except the most recent one will be cleaned up. Convert the pre-processing actions completed by the user on the Web interface into a format recognizable by the Ansys software. This conversion process involves generating a script written using the Ansys ACT Python library. All pre-processing operations will eventually be merged into one script. This script basically includes several stages, which are equivalent to the pre-processing process of the simulation, that is, the script includes:

[0162] Import of geometry files;

[0163] Mesh generation and refinement adjustment;

[0164] Setting of boundary / load conditions (i.e. setting of force / pressure / degree of freedom, etc.);

[0165] Set the analysis type, such as static analysis / steady-state thermal analysis / buckling analysis / display dynamic analysis, etc.;

[0166] Set the solution target, such as stress / temperature / deformation / fatigue, etc.

[0167] The script is executed with the help of the software interface provided by Ansys to simulate the user's pre-processing operations. This process ultimately generates an input file that can be solved without the user having to perform any Ansys interface operations.

[0168] In this way, the present invention not only significantly simplifies the complexity of simulation pre-processing, but also makes the engineering simulation process more efficient and user-friendly, further improving the accuracy and reliability of the simulation work.

[0169] A specific embodiment of Ansys pre-processing of the present invention:

[0170] In the core implementation process of the present invention, the solution stage is also very important, which cleverly connects supercomputing (supercomputing) resources to ensure high efficiency and high precision completion of simulation tasks. Figure 4 As shown, the process starts with converting the model and settings completed by the user in the pre-processing stage into a solution input file. These files accurately encapsulate all the necessary information for the simulation task, including but not limited to boundary conditions, material properties, and meshing. This is also part of the Ansys ecosystem. Ansys ensures that this input file includes all the above information. Customer needs are almost all subsets of these capabilities, and there will be no unencapsulated situation.

[0171] After completing the pre-processing, the present invention uploads these solution input files to the connected supercomputing resources. The smooth execution of this step marks that the simulation task has officially entered the computationally intensive solution stage. With the support of supercomputing resources, Ansys software is used to perform complex simulation operations, and its high-performance computing capabilities ensure that even the most complex simulation tasks can be completed within a reasonable time. The use of supercomputing not only significantly improves the efficiency of solving, but also ensures the accuracy and reliability of the simulation results.

[0172] like Figure 5 As shown, a specific embodiment of Ansys post-processing of the present invention:

[0173] The post-processing function of the present invention not only demonstrates the efficient processing capability of common, visual file formats such as VTK, but also can immediately obtain and convert the solution result file after the simulation solution is completed. By utilizing the open source post-processing Python library provided by Ansys, the present invention can accurately convert the Ansys post-processing result file into the widely supported VTK visual file format. This process ensures seamless conversion of data and its high-quality visual display on the Web side.

[0174] A specific embodiment of Web post-processing of the present invention:

[0175] As VTK format files are generated and transmitted to the Web end, the present invention uses rendering technology to efficiently display these files in the browser, thereby achieving intuitive visualization of the simulation model results. In addition, the present invention further enhances the depth and breadth of post-processing analysis by generating a detailed post-processing report. The report not only presents the key views and data analysis of the model results, but also includes a comprehensive evaluation and suggestions for the results. Different reports will be generated for different customized scenarios. For example, for the scenario application of statics, the report will state the extreme values ​​and static screenshots of stress and displacement, and the report of thermodynamics will state the extreme values ​​and static screenshots of temperature; the evaluation criteria will also be different. For example, the evaluation criteria for statics often look at whether the maximum stress value exceeds the yield strength of the material; the evaluation criteria for thermodynamics will look at whether the extreme value of temperature exceeds a threshold, which will cause overheating material damage or other situations, providing simulation engineers with a comprehensive analysis tool.

[0176] This design enables simulation engineers to not only directly access and analyze simulation results through the Web interface, but also to conduct more in-depth analysis and evaluation based on the generated post-processing reports. Combining these functions, the present invention significantly improves the efficiency and effect of simulation post-processing, enabling engineers to make decisions more accurately and quickly, and optimize design and performance.

[0177] The present invention successfully realizes the full cloudification of the Ansys simulation process, covering the entire process from pre-processing, solving to post-processing. This fully cloud-based solution provides a coherent and seamless workflow, allowing users to complete all simulation steps through the cloud platform. In particular, in the solving stage, the present invention makes full use of supercomputing resources to ensure the efficient execution of complex simulation tasks. Although this process relies on powerful computing resources, the integrated use of the cloud platform provides users with an easy way to access and use these resources without directly investing in expensive hardware. This not only optimizes the allocation and use of resources, but also makes advanced simulation functions more popular. Regardless of the user's hardware conditions, these high-performance computing resources can be accessed and utilized to complete complex simulation tasks.

[0178] The present invention greatly simplifies the user's operation process and usage cost by introducing a pure Web client access method. Users can directly access the simulation platform through a browser to set up, solve and analyze the simulation model without downloading and installing any special software. The Web terminal includes the following functions: rendering geometric models and supporting rendering; zooming and rotating viewing angles; selecting specific geometric bodies or faces. This Web-based access method not only improves the user experience and reduces the simulation preparation time, but also significantly reduces the maintenance and update costs of the software. For users with relatively limited resources such as small and medium-sized enterprises and educational institutions, this innovation provides a low-threshold, high-efficiency simulation solution.

[0179] The present invention provides a solid theoretical basis and practical engineering solutions for the simulation of customized scenarios. Through the cloud platform, users can quickly customize and execute simulation tasks according to specific engineering requirements. This not only includes simulation of specific industrial applications, but also covers specific needs in the fields of education and research. The architecture and workflow design of the present invention make the simulation customization for different scenarios more flexible and efficient, providing strong support for solving complex engineering problems.

[0180] like Figure 6 As shown, a specific embodiment of applying the present invention to perform heat transfer analysis on a pan:

[0181] Based on the method proposed by the present invention, the present invention conducts a detailed heat transfer analysis on a frying pan to verify whether its design meets the expected heat transfer performance. The following are the specific steps of the heat transfer analysis:

[0182] The first step is to upload the pan model, which includes the following:

[0183] The user first uploads the pan model file designed in the computer-aided design (CAD) software to the present invention. The present invention performs model analysis in the background to extract key feature points and related data in the model. The process has the following steps: using the Ansys interface, extracting the relevant data of all geometric bodies / faces of the pan, including the centroid coordinates of the body, the volume of the body, the center coordinates of the face, and the area of ​​the face; these feature data will be saved in a searchable database for subsequent comparison and matching.

[0184] The second step is to select the pan heating source and set the heating power, which includes the following:

[0185] The user defines the heating wire at the bottom of the pan as a heat source and specifies a specific heating power, such as 500 watts, to simulate the heating conditions in actual use.

[0186] The third step is to select the pan heating body and set the heat transfer coefficient, which includes the following:

[0187] The pan body is selected as the heat receiving body, and the user needs to set its heat transfer coefficient, for example 0.0005W / (m 2 ·K), which is crucial to the simulation accuracy.

[0188] The fourth step is to select the materials of the heat source and the heat receiving body of the frying pan, which includes the following:

[0189] To ensure the accuracy of the simulation results, the user sets the material of the heating wire and the pan body to aluminum alloy, which should match the material planned during specific production.

[0190] The fifth step is to submit the simulation calculation and wait for the calculation to be completed, which includes the following:

[0191] After completing all necessary simulation parameter settings, the user submits the simulation task through the Web client of the present invention. The present invention performs Ansys pre-processing in the background, generates a solution input file, generates a .dat format file, and submits it to the supercomputing center for solution. The user then waits for the calculation to complete and obtains the result.

[0192] The sixth step is to observe the heat flow analysis cloud diagram of the heated body, which includes the following contents:

[0193] After the calculation is completed, the present invention converts the result file into a universal VTK format and renders it in the Web client. The corresponding extended description is also provided in the previous text and will not be repeated here. The user can intuitively observe the heat flow cloud map of the heated body of the frying pan to evaluate the heating effect.

[0194] The sixth step is to analyze the heat transfer of the pan, which includes the following:

[0195] Generate a detailed heat transfer analysis report, which not only graphically displays the simulation results, but also compares with relevant national standards. The report includes two core data: one is the maximum temperature, which will affect whether the pan will overheat during use, causing side effects such as food coking, and the other is the temperature distribution map, which will serve as a reminder for pan manufacturers to know which areas need to use high-temperature resistant materials and which areas can use ordinary materials. Through this report, users can clearly judge whether the pan design meets national standards. If there are heated areas that do not meet the standards, the present invention will specifically point them out for subsequent design optimization.

[0196] Through the method provided by the present invention, users can efficiently and accurately complete the heat transfer analysis and evaluation of products such as frying pans, ensure the rationality and compliance of the design, and further optimize product performance.
