Hi all,

I'm trying to run a eigenfrequency analysis on a solid part. The meshing worked, the material is defined, as well as fixed constraints.
But when I want to compute, I get the error message " The mass matrix is zero".

If anyone would know what the problem is, that'll be really nice !
Thanks

Hi Rozenn,

I would argue that the material is not assigned to a domain.
If this does not help - contact us via the Support Center (link at the bottom of this page).
