Hello,

Here are few general steps that you can follow. But before that , configure your ANSYS Workbench project with parameters and outputs and ensure the ANSYS toolbox is installed in MATLAB for communication.

Define Genetic Algorithm:

Create an objective function in MATLAB that:

• Updates ANSYS parameters.
• Runs the simulation.
• Retrieves results and calculates fitness based on desired vs. actual results.
• Use MATLAB's ga function to set up the genetic algorithm with appropriate bounds and options.

nVars = 5; % Number of parameters to optimize
lb = [0, 0, 0, 0, 0]; % Lower bounds
ub = [10, 10, 10, 10, 10]; % Upper bounds
options = optimoptions('ga', 'Display', 'iter', 'PopulationSize', 50, 'MaxGenerations', 100);

[optimalParams, fval] = ga(@objectiveFunction, nVars, [], [], [], [], lb, ub, [], options);

To automate the interaction, write MATLAB functions to update parameters, run simulations, and retrieve results from ANSYS using the toolbox or scripting.

Execute and Analyze:

• Run the genetic algorithm and monitor its progress.
• Analyze and validate the optimized parameters and results.
• Visualize the comparison between desired and actual outcomes.

This process allows MATLAB to iteratively adjust ANSYS parameters to minimize errors effectively.
