Hello,
Well, I actually tell you in my last post that this keyword is no longer used...
You can look into subroutine condim.f examples that have been put with comments. You can remove the comments to activate them, and change them depending on what you plan to do. You can also look how it is done in the example t3d_cooper, in steering file t3d_cooper-hyd.cas and corresponding Fortran file. If you have fixed planes in condim.f the only extra thing to do is adding :
MESH TRANSFORMATION : 3
in the steering file.
With best regards,
Jean-Michel Hervouet
