Problems solved by technology

Just like the current popular optimization method of MATLAB combined with HFSS simulation, it is necessary to use HFSS’s own functions to record the VBScript script at the beginning of the establishment of the HFSS project; all operations such as the establishment of the optimization model, the setting of solution conditions, and the export of calculation results are all recorded in VBScript script; and then edited to import it into the MATLAB optimization program, and finally import the offspring population variables into the optimization project, that is, to reassign values ​​for the optimized variables in the script, and then run the script to solve and export the results to find out The fitness value, the calculation and optimization process is extremely complicated and cumbersome
At the same time, due to the instability of the VBScript script carrying the offspring HFSS project information, it often leads to high complexity in project import and optimization environment establishment, and has high uncontrollability

Abstract

The invention belongs to the field of HFSS project simulation design parameter optimization, and particularly relates to an optimization algorithm based HFSS project optimization method. The method comprises the following steps: a project importing step; a variable input step; an HFSS simulation fitness calculation step; and a stop condition judgment step. Therefore, the optimal fitness value of past populations is obtained and output as a result. Through the scheme, the situation of optimization program termination caused by calculation errors generated due to instability of VBScripts carrying sub HFSS project information can be effectively avoided; and the internal parameter optimization efficiency can be improved while the simulation design is simplified.

Description

technical field [0001] The invention belongs to the field of HFSS engineering simulation design parameter optimization, and in particular relates to an optimization algorithm-based HFSS engineering optimization method. Background technique [0002] HFSS (High Frequency Structure Simulator) is a three-dimensional electromagnetic simulation software launched by Ansoft. It is not only the world's first commercialized three-dimensional structural electromagnetic field simulation software, but also the most popular design software for antenna design today. As the functions of HFSS become more and more powerful, more and more applications are used, and the models constructed become more and more complex, there are more and more variables affecting a certain parameter in an HFSS project file. However, when the number of parameters increases and the optimization variables are complicated, the entire optimization process cannot be completed by only using the optimization function of...
