Ok, will try.

Yes, you are right because the formula reported in line 195 is not
dimensionally correct.

I have no idea. Another way is non-dynamic control of stress in the period.
Ok, will also try to make use of the non-dynamic stress control. Now,
looking at the formula in line 190 of PeriIsoCompressor, it does not look
dimensionally correct either. Can anyone correct me if I am wrong? Does it
matter, at this point, if the strain rate is updatd in such a way that the
additional term is dimensionally incorrect?

Thank you very much for your answer,
Chiara
