Mesh refinement of two-dimensional polycrystalline model

[ZJM-19491001]

Dear friends:
I 'm a newcomer to neper. I want to know how to divide a region or a grain into denser grids in a two-dimensional polycrystalline model, while the other parts use coarse grids. I have tried -domface/cut orders... But it was not successful, besides, I need CPE4 element.
I 'd appreciate it if someone could answer that question! Thank you very much!

You can define the element size using a custom -rcl value. For example, to refine grain 1:

neper -T -n 100 -dim 2 -reg 1
neper -M n100-id1.tess -rcl "((id<=1)?0.2:2)" -pl 10
neper -V n100-id1.tess,n100-id1.msh -dataelt2dedgerad 0.001 -dataelt1drad 0.003 -showelt1d all -print d

Neper only generates triangular elements in 2D, but you should be able to get quads as described in this discussion.

Dear Dr. quey :

Thank you for your reply and thank you for your hard work for neper!

Yours, sincerely.
