Yes. My concern was the off-diagonal strain (exy) not being the same as the normal strain despite the rates being equal. Am I wrong in assuming that exy =0.5 (O.cell.trsf[0,1] + O.cell.trsf[1,0])? (The factor of 0.5 is missing from my script but that is not the main point). About the 2nd question; cell.trsf is the time-accumulation of cell.velGrad. So, for a fixed cell.velGrad and fixed number of steps, if I reset the reference trsf point by O.cell.trsf=Matrix3.Identity, it should not affect the resulting change in dexy. Which is not the case if you compare the two results you mentioned.
