Modal analysis to calculate the eigenfrequencies and eigenshapes of a structure is a very basic analysis type. Simscale used in the past the Calculix solver for this analysis type. Any background why such a fundamental analysis type (see What Is Modal Analysis and Why Is It Necessary? | SimScale Blog) is no longer supported by Simscale?
Indeed this feature is not part of our modules inside SimScale anymore - it simply has not been used that often. If you are still interested in this feature and would like to have it back I would highly recommend to put your wish into the Vote For Features category.

Any update on whether modal analysis is coming back to SimScale? I created an account just for this type of analysis and am slightly disappointed that it is no longer available. I’ll have to give ANSYS Fluent a try.
I have not seen the release notes discussing this feature yet but I have tried it out a couple of times with some success.
One thing I have not figured out is how to display the deformed mode shapes. I am able to view the first mode but I can not find a way to show any other modes. Can you provide some guidance on showing the mode shapes?
there is currently a limitation in the post-processor that you have to delete first the animation of the previous mode and then create a new one for the newly selected frequency. This might be the reason for your issue.
