Enforced displacement Question Nastran
Enforced displacement Question Nastran
(OP)
Dear All,
I have two quick question on enforced displacement for non linear contact analysis SOl 600 (MD) or SOL 601 (NX).
1. is it okay to add enforced displacement on a contact surface.
2. If I only want to go in the x-direction (3)mm is it still common practice to add zero's on the other five DOF.
Thanks,
THECADGUY

RE: Enforced displacement Question Nastran
It is not possible to impose enforsed displacement on contact surfaces.
The reason for that is that nastran will internally create MPCs between the master-slave surfaces and if you assign an enforced motion you will end up with a dependecy error.
Hope this helps..
