Penetration in model after defining thickness
Hi,
I've working with a model defined with shell finite elements on Hypermesh 13 and have been having trouble after the definition of the properties cards of the model. When I specify the thickness of the surface, a lot of penetrations (on more than 2000 elements) appear on my model and the automatic fix tool doesn't seem to work on them. I've verified and there aren't any geometrical intersections on the surfaces. My questions are:
How can I avoid such problems or configure the model in order to prevent them?
When defining the thickness of a surface, this surface is assumed to be a mid plane so the thickness is distributed equally to both sides? Can this be modified?
Thank you in advance for your help.
