All,

I have a fairly simple assembly with 44 parts.  nothing fancy. all solids.  I create a mesh, and the mesher completessuccessfully and you can view the mesh, and no warning or errorindicators are on the mesh portion of the tree.  However, whenI right-click to run analysis, I receive a pop-up saying,"Mesh Information not available", and a red X appears inthe tree.  

This also happens when I use the "Run analysis after meshingcheck box".

Note:  This does not happen every time.  

Please explain.  If needed I may be able to post the model.
