Is anyone out there using pyramids? I've got a hybrid hex/tet/pyramid mesh in exodusII format. (ExodusII has undocumented support for pyramids, meaning I guessed at their node ordering since it is not in the old documentation.) So now I get negative Jacobians on a *subset* of my pyramids, which I know have positive volume.
So there are two obvious sources of error (1) the nodal ordering in the file, or (2) the shape function gradients themselves. However, it is not clear at the moment since only a fraction of the pyramids show up bad. I'd be interested to know if anyone is successfully using pyramids in their calculations since this will strongly implicate (1). Thanks. -Ben ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
