Lei Hang is still having a problem:
Thank you for your answer! I have some other questions.
1. What is the meaning of the numbers(2,3,4,5) in
"hsize[2]","hsize[3]","velocity gradient [4]","deformation gradient
[5]"? Are they the order of attributes in this script? Does "hsize" mean
the size of cell? Does "diagonal terms" mean the size of cell?
2.
"> In the "Checkstress()" part, it changes to "O.cell.velGrad=Matrix3(0,0,.1,
0,0,0, 0,0,0)"
now it is changed to shear:
diagonal terms are zero = no change of size
non-diagonal terms are non-zero = some shear or rotation (in this case only
one, xz, non-diagonal term is non-zero = shear in xz plane)."
Here, how to determine it shears in xz? Why is it shearing rather than
rotating? Why is it in the xz plane rather than in other planes?
