Hello,
There is a bug in SALOME 9.8 about the local refinement on a face with NETGEN2D. I prepared an HDF example to reproduce the bug but I’m not available to upload because i have a new account… So to reproduce the bug i put the script below. If you load the script in SALOME 9.7 you will see a nice refinement on the little pipe (on Group_1) whereas with SALOME 9.8 you will see that the refinement is not correct.
Thank you for your help,
Regards
Yohann EUDE
Here the script:
