Hello, 

thank you for response, however i had read instructions provided in this link previously and it didn't help me to understand what is wrong.

Is there any option to see the inside how the deformation gradient or the stresses are calculated for shell elements for *mat_soft_tissue (material 91)? It would help to understand in which line of my umat procedure i am making some errors.

Best regards,

Tomasz Wiczenbach
