An authoring system and method that allows users to select and arrange three-dimensional objects with corresponding fire attribute information, converting this data into an FDS input file for simulation, enabling non-professionals to author and utilize high-precision fire-dynamics-simulation content by simplifying the process of setting fire attributes and environment settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If professional knowledge is required to set fire attributes for materials, then the precision and accuracy of fire-dynamics-simulation results are improved, but the ease of operation and accessibility for users without expertise deteriorates
Solution Approach 1:
The patent introduces an automated content authoring system that acts as an intermediary between users and the FDS simulation process. The system automatically extracts fire attribute information from three-dimensional model data and material databases, eliminating the need for users to manually set complex fire attributes while maintaining high precision. This mediator handles the professional knowledge requirements internally, allowing users without expertise to perform accurate simulations.
Solution Approach 2:
The system enables self-service content authoring by automatically generating simulation input files from three-dimensional model data. The automated process extracts material information, determines fire attributes, and creates FDS input files without requiring user intervention or professional knowledge. Users simply need to provide basic model data, and the system handles all complex fire attribute settings autonomously.
2Manufacturing precision
If manual setting of fire attributes is required, then the accuracy of simulation input data is improved, but the productivity and efficiency of content creation deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-extracting and organizing fire attribute information from three-dimensional model data and material databases before the actual simulation process. Material properties, thermal conductivity, specific heat, and other fire-related parameters are automatically identified and prepared in advance, ensuring accuracy while eliminating time-consuming manual setting during the content creation process.
Solution Approach 2:
The patent replaces the manual mechanical process of setting fire attributes with an automated computational system. Instead of users manually inputting and configuring fire attribute parameters, the system uses automated data extraction, pattern recognition, and database querying to generate accurate simulation input files, dramatically improving productivity while maintaining precision.
3Reliability
If complex fire attribute information must be configured manually, then the reliability of simulation results is improved, but the device complexity and system requirements deteriorates
Solution Approach 1:
The system segments the complex content authoring process into distinct modular components: three-dimensional model data processing, material database querying, fire attribute extraction, and FDS input file generation. Each module handles a specific aspect of the process independently, making the overall system more manageable and maintainable while ensuring reliable results through systematic processing of each segment.

AI summary
A method, performed by an authoring system, of authoring content for a high-precision fire-dynamics-simulation (FDS) is provided. The authoring system selects a target object from an object DB storing a three-dimensional model of each object made to correspond to surface information indicating at least one material constituting a surface of the three-dimensional model and material information indicating fire attribute information of each material; arranges the selected target object in a three-dimensional space to author content for the FDS; converts the content for the FDS into an FDS input file used as an input for a simulator for the FDS; and outputs the FDS input file to the simulator.
