Sigrity: Tip of the day – Using Parametric Sweep in Sigrity PowerSI

It is not always possible to predict the right parameter values to get a desired output in simulation. You must run multiple simulations with different combinations of parameters to get the results that satisfy your requirements. However, it requires a lot of manual effort because you must change the value of the parameter and then run the simulation. After several iterations, you might need to plot every result in a single graph for further postprocessing manually.  

Have you ever thought about an alternative option to automate this process, which might reduce the manual efforts and be more efficient? The Parametric Sweep option in Sigrity PowerSI will be that alternate method, which saves your time by simulating multiple SPD files with different combinations of parameters.  

For example, in Sigrity PowerSI, do the following: 

• Go to Setup > Sweeping Manager. 
• Select the parameter type. 
• Add parameter values. 
• Generate SPD files. 
• A directory will be created with the batch script. Run the *.bat file for parameter sweep. 
• You have the option to load the sweeping results after the simulation. 

This function should help you to get simulation results based on the selected combinations of parameters.
