COMSOL Script Eigenfrequency Display

[GDC]

Hello all, I am having a hard time coming up with the proper syntax in order to have COMSOL Script spit out the various eigenfrequencies for a static/eigenfrequency analysis that I am running. Previously I have been using:

postmin(fem,'eigfreq_smsld')

this works well for recording the fundamental frequency of my structure in Hz. However, I am now interested in obtaining a list of the eigenfrequencies relating to the various solution numbers and I am having a hard time locating the proper command.

Your suggestions are greatly appreciated!

The command you need is postmin(fem,'eigfreq_smsld',n). The n parameter defines which solution number you want the eigenfrequency for. For example, postmin(fem,'eigfreq_smsld',1) will return the eigenfrequency for the first solution, postmin(fem,'eigfreq_smsld',2) will return the eigenfrequency for the second solution, and so on.

Hello, thank you for reaching out. In order to obtain a list of eigenfrequencies for your static/eigenfrequency analysis in COMSOL Script, you can use the command "eigfreqs" followed by the solution number. For example, if you want to obtain the eigenfrequencies for solution number 1, the command would be "eigfreqs(1)". This will provide you with a list of all the eigenfrequencies for that solution. Additionally, you can use the command "eigfreqs(1,1)" to obtain the first eigenfrequency for solution number 1. I hope this helps and please let me know if you have any further questions.
