Extracting Deformed Mechanical Eigenmode Geometries

Hello All,
This particular question has been maddening for me. I would like to do the following. Draw an arbitrary geometry in Comsol, find the mechanical eigenmodes of that geometry, then extract the deformed geometry of the nth eigenmode, and then use that deformed geometry as an initial condition for a subsequent problem. This problem is maddening to me because, in principle, all the information is there. I can run an eigenvalue simulation and I can then look at the u,v,w displacement vectors - so all the information is there - but it seems very hard to extract this deformed geometry and use it in another calculation. Does anyone have any ideas?

Hi
I would propose that you take a lokk to the user manual with the key word "Remeshing a Deformed Geometry" that should help, at least partly ;)

Good luck
