Simulate the 2D contact composite material
Simulate the 2D contact composite material
(OP)
Dear all,
I want to simulate the contact between 2 body in 2D problem by Nastran (SOL 400). One of the 2 body is composite material, but untill now i don´t achieve it.
If i use 2 metal body, i have results, but when i use the composite material, Nastran doesn´t work.
Any body have any idea about this problem?
Please help.
Thank you

An example of an error message would be,
USER FATAL MESSAGE 9050 (SEKRRS)
^^^ RUN TERMINATED DUE TO EXCESSIVE PIVOT RATIOS IN MATRIX KLL.
^^^ USER ACTION: CONSTRAIN MECHANISMS WITH SPCI OR SUPORTI ENTRIES OR SPECIFY PARAM,BAILOUT,-1 TO
CONTINUE THE RUN WITH MECHANISMS
After some research, you will find this is a problem regarding unconstrained rigid body motions.
