paraview imposed strains

[rwendner]

the paraview output for the imposed strains and strain increments is off by one step in the MFEM framework.

In the attached example, T is increased by 0.1 deg C per time step (paraview).
The stresses are consistent with the T increase - the strains are behind.
E.g. in step 3, T = 0.3 and sigzz = -90 but the vol eigenstrain is 6E-4 (should be 3*0.3E-3).
also the strains and strain increments are zero of the first two steps

I suggest you also check if the same problem exists for the MLDPM framework.
