Thanks for the answer, Robert! And excuse me for the long response.

I'm not sure, that I understand you clearly.
I have added changes from Git, and the computation of determinant in my programm is correct now. And your "black magic" code don't produce error any more. So you kill this old bag, right?) And strain can be used for futher computations now? Thank you very much!

As for the terms and issues, I compute determinant and other values for the energy calculation. If it is possible to make terms for the energy density function for hyperelastic material, it would be great and I'll add the issue as soon as I can:)
