Two steps in one study

Please login with a confirmed email address before reporting spam

Hi , I am currently working on a model using the Solid Mechanics and Eigenfrequency study in COMSOL. I want to compress a beam first and then fix it in its compressed state to check the eigenfrequencies. Is it possible to set up such boundary conditions in a single study with two steps? any hints will be appreciated

The Eigenfrequency, Prestressed study does exactly that.

Dear Henrik Sönnerlind , Thanks for your reponse ,I already did that but I'm getting this erros :

  • Feature: Compile Equations: Eigenfrequency (sol34/st2) Errors when compiling equations. Multiple moving frame specifications on the same selection.
    • Selection: Domains 1–3 I'm quite new to COMSOL and not sure what the problem could be.
