MSC NASTRAN linear contacts issue
MSC NASTRAN linear contacts issue
(OP)
Hi all,
I need some help.
I am trying to use MSC NASTRAN linear contacts(BCONTACT, between surfaces and between a surface and a solid) in a model and It's giving me back the following error.
The model is quite large so I suspected that the problem could be related to that, but our computer is able to run a SOL101 without any problems. On the other hand, the contacts are defined in a small area so I suppose that neither is the origin of the problem.
¿Do you know what could be the cause?
I use the following cards and parameters (Note that BSURF cards are used but not included)
I would appreciate your help.
Thank you in advanced,
Regards,
