Surface contact simulation

[jonmwilson]

I have been trying to simulate a force pulling on a block that is bolted down to a flat surface. When I apply a surface to surface contact between the block and the ground, the simulation will run with no errors but the results will not load.

The same simulation can be run without any contact constraint and produce results but the two parts will intersect one another. I need the surfaces to remain touching but not merge together. Can anyone help me?

Dear Jonmwilson,
To see the reason of the error you will have to take a look to the simulation output results files (ASCII format), I suppose you are running NX NASTRAN solver, then check the *.f06 file and look for FATAL word in the file, it is an ASCII file that you can open using notepad.exe or similar. The reasons of the error could be many, a typical one is that not enough RAM memory assigned to the NX NASTRAN solver, simply increase the size in the "Edit Solver Parameters" window.

Best regards,
Blas.
