Inconsistant Result

Hello Everyone,

Ok here is some more detail on my previous post which didn't attachthe file properly. I am applying the same load to 4 individual thinmembranes that are all the same material. It actually doesn'tmatter what material it is I always see the same thing. One of themembranes has a displacement that is not the same as the others. Itseems to be mirrored in the XY plane which is an incorrect result.The other membranes do show what would be expected. Any Ideas howto resolve this inconstancy. Open the Basic assembly then go to thecosmos tab and open the displacement figure you will see what I amtalking about.
Thanks,
