esqr - definition changed from version 9.2 to 9.3?
 
I am using customized routines, which evaluate the generalized strain variable ESQR (see mucal.f). When I stepped from version 9.2 to 9.3 the code did'n work anymore. It seems that ESQR produces different values. Was ESQR changed from 9.2 to 9.3? Any comments?

Andreas,

Yes, ESQR in 9.3 denotes the square root of the second invariant of the strain rate tensor. Before, it was the invariant itself.
