how to get the strain of random region in FEM part about dem-fem-coupling HOT 3 OPEN

I don't know of a "direct" method, but probably there is some.

You can try:

• find an element containing the coordinates using spatial localizer and localizer.giveElementContainingPoint(pos,None)
• do standard FEM interpolation on the elment. I don't see the way in python after a (very) quick search, so you can:
  • get nodal coordinates and nodal values
  • knowing the type of the element, and nodal values, interpolate "manually"

Sorry Jan, i want to give up it. It too hard for me. It may be a little impolite, but i still want to consult that if it possible to hire you or somebody else you familiar to help me finish the code part. I have tried my best to realize my idea, but it too difficult for me. Forgive me for speaking directly, sorry for that.

Ok, no problem.
The code itself is not meant as a ready-to-use solution (or for some specific cases) and needs some contribution from the user..
Currently I have no resources for such a work.

You can contact Oofem people, see links discussed here.
Also note that both relatively old and modified version of oofem is used for this project.

good luck
Jan
