Hello, To get the Cauchy stress, we have to evaluate the term *ev_cauchy_stress*, however, it does not seem to be compatible with a shell10X term-based problem. Is there a way to get Cauchy stress and strain when dealing with a shell model? Best regards. Guillaume Gbikpi-Benissan -- Junior Researcher (Postdoc) RUDN University Moscow, Russian Federation

Output for running failed test_homogenization_perfusion.py in raise mode

by Roshan Suresh Kumar

Hi, During my installation of the latest version of sfepy from source (GitHub repo) in Windows, I ran the command to test the various modules. I found that one test had failed, the one for test_homogenization_perfusion.py. I ran the test in raise mode and the output is show below. P.S.: I installed all of the optional dependencies except igakit, petsc4py, slepc4py, pymetis, scikits.umfpack and pysparse. I hope this helps. Let me know if you need any other details. Thanks.
