LoadKM: negative dimensions are not allowed about pymapdl HOT 11 CLOSED

Could you please upload the full file here?

from pymapdl.

Yes, of course

elem.zip

from pymapdl.

It appears that there's no mass matrix in the file. Item 34 of the header of a symbolically assembled file is the number of mass terms, and it's 0 for this full file. I'm going to modify the reader so that it gives a warning when there are no terms in the mass matrix and update the code here on GitHub.

Were you interested in only the stiffness matrix, or did you want to have the mass matrix as well? If so, you might want to double check to see if you can output that from ANSYS.

Closing soon unless I hear otherwise.

Sorry for the late answer.
It works, and I found the problem in ansys. When u wrote the full file not contained the mass matrix, i knew immediatelly why. I started a structural analysis and for this analayses not wrote the mass matrix ion the full file. After I started a modal analyses and it has worked. I need both so now i'm happy :)
Thank you for the answer and the quick help and sorry the late response.

When i started to run the attached fullfiles, sometes i got this message:
"Kernel died, restarting"
Do u have any idea, what can cause this error? Sometimes it is works, but another time it is not.

Do you have any idea?

Yes, it's due to DOF constraints. I'm working on fixing it.
