Hello,

Some screenshots have been attached here to see how weird the mesh displacement interpolation behaves.

Hello Yvan,

Do you have any suggestion of the problem encountered with the field displacement within an IFS calculation please ? I have enclosed herein some pictures of the displacement field.

Thank you in advance.

Hello,

I wonder if this is not related to a very recently discovered (but old) bug, whose patch is here: https://github.com/code-saturne/code_sa ... 15c743bb09.

You can try to apply the same modification manually to your sources and reinstall (or for initial testing, adding the modified file to your SRC folder). If your pull the 5.0 branch (the one you are using I beleive) for GitHub, I think the patch has been merged.

This could explain some of the issues you observe, so I recommend checking this first.

Best regards,

Yvan
