Error in calculating cauchy stress. Wrong arguments shape
Hi all. I keep getting this error with the latest version of sfepy when I run the following lines. Could you guys please help.
strain = pb.evaluate('ev_cauchy_strain.{dim}.Omega(u)'.format(dim=dims), mode='el_avg')
The above line works fine.
stress = pb.evaluate('ev_cauchy_stress.3.Omega(m.D, u)', copy_materials=False, mode='el_avg')
but the stress line always shows the error below. m is defined before in the problem with 'D' value.

Note that the number after the term name has nothing to do with some dimension (assuming from your naming) - it is the numerical quadrature order.

The D shape has to be (6, 6) in 3D or (3, 3) in 2D - can you check that?

Hi Robert,
Thanks for your reply. I have checked and it is (3,3). I am calculating D from stiffness_from_youngpoisson.
Thanks Samyak

Hi Robert,
I did check it again and my mistake was that stiffness_from_youngpoisson with first parameter as 2 and hence (3,3). I have changed it now and it is fine and works perfectly fine. Thanks a lot.

OK, glad you solved the problem!
