When I calculate the stress of a bean that is on one side fixed and has a face load on the other end.

- when performing a stability analysis the resulting displacement is exactly the same as CalculiX computes

however, when I perform a modal analysis

- the eigen frequencies are also exactly the same as CalculiX computes

- the displacements of the different mode are completely different ( also not just a factor 10 etc. smaller/larger)

I assume that I have to perform a calculation to get the displacement for a mode in meters? So what values are in the eigen mode displacement result mesh and how to I have to calculate them to get the displacement in meter?

Here is my case.sif file:

I have I tested with this Elmer version:
