Dear all,

do you know does any entry stored is STATEV, used in UMAT subroutine,
should remain unchanged for the next increment for the case of finite
deformation?
I know that STRESS and STRAN  will be rotated by ABAQUS but what about the STATEV?

I want to protect STATEV from any rotation by ABAQUS in order to rotate
it in UMAT by my rotation matrix but I am experiencing that it is
different value at the beginning of new increment in comparison the one
as output from previous increment.

Thanks in advance,

Marina.
