Bug: Stress stiffening in modal vibration with CCX and normal pressure.

Bug 16 listed here: http://mecway.com/product.html#bugs

It seems to be a problem in CCX. A workaround is to use XYZ pressure (traction) instead since that's exported to CCX as *CLOAD instead of *DSLOAD which has the problem.

Here's an example showing how tensioning a bar reduces its natural frequency when it should increase it.

    Have you received an answer from the CCX forum? During last period I didn't follow any forum

    Only one, which I think confirmed it.
