fatal error 9994 BULKPM

[khashpj]

Hi
I have a model made by beams elements. When I perform a linear static anaysis (Sol 101) everything seems to be correct.
But as I change the solution type to sol 103 I face fatal error 9994 (BULKPM)
Do you have any idea what is wrong with the model?

Thank you

Can you post relevant sections of the f06 file? Also what version of nastran are you using?

Have you defined mass density? A sol 101 doesn't require mass, while sol 103 does.
