Hi, I have solved it by tuning again the parameters involved.
However I have another problem now (I use this thread as it is related to
the servo-control). I would like to assign stress increments in order to
follow a specific stress path (different from the triaxial one) in
stress-control. Would you have any suggestion how to do that using
TriaxialStressController?
Thanks,
Chiara
