dan.wang is still having a problem:
Hi

The question is, in the first file, when I calibrated the parameters  of
the RVE, I can get the strain and stress at each step. For example, the
strain is [0,1e-5,0] at first step, the corresponding stress is [0 1e3
0];

Then I use the strain to calculate the stress using the method in the
second file:

dstrain = utils.Matrix3(0,0,0,0,1e-5,0,0,0,0) 
O.cell.velGrad=dstrain/(ns*O.dt)
O.run(ns,True)

and the stress I get from this way is not [0 1e3 0], but another one.

So I am confused, that the RVE I calibrated, which is applied to the
same strain, the stress is different?

Thank you for your help!
