Calculation of Eigenvalues

Hi There,
I applied an area load in SOFiLOAD, and i wanted to convert it to a mass while computing the eigenvalues : MASS LC 2 SELE PZZ MX 100 [100%] MY 100 [100%] MZ 100 [100%]
but the software said : Loadcase 2 has no suitable nodal loads to be converted. Can you please help me.

As far as I know, the loadcase has to be calculated by ASE before.


You are right, i have calculated it in ASE but it didn’t work

Generally gmay is right. So if you expect more help you should upload your system :wink:
