As Kevin wrote there is no orthotropic material models in plate and shell solver. There could be, just hasn't been any projects to push this. -Peter

Thanks, that is what I saw in the code, but the manuals imply there might be. Also, the solvers read the matrix input of Youngs Modulus without error or reporting that it is not supported, I suppose that is because they use the standard input function call.

Thanks for the definitive answer, I also looked and only found perforations code, no general stiffness matrix. Manual hints that both are supported though.

I was able to copy the Smitc.F90 solver to my working directory renamed
MySmitc.F90
added a subroutine, and forced the code to call it. I hard coded the Ematrix, and received the correct solution.
I then modified the E22 and E33 terms and the answer changed accordingly.

I copied the perforated subroutine, but hard coded the Ematrix instead of letting the original code calculate it.
Not an ideal solution, but seems to work.

Sounds like it wouldnt be too much effort to add the stiffness matrix input to the next version. (Hint, hint :) )
