Hi

I am trying to validate a bulk modulus calculation on a simple cube of a linear solid. I apply a uniform force per area on all six sides of the cube (all in compression). But I cannot get the model to solve, it keeps failing because the relative error is greater than the relative tolerance. Any ideas?

I'm sure this is some simple thing I am overlooking.

Thanks
Chris

If you are doing a stationary analysis you need sufficient boundary conditions to make the model stable. For your case you can model one eighth of the cube and apply symmetry boundary conditions on the 3 cut faces.
