I am trying to implement the stop condition in the fluid structure interaction(fsi) mode? My idea is to stop and remesh the geometry when the mesh of the fluid becomes too bad.
Howver when I follow the instructions on page 648 of Users mannual of version 4.1 by entering "mod1.ale.minqual-0.1" to the stop expression, the program refuse to run and report an error. If I remove the stop condition, it run well.
What is the expression for this in fsi mode?
Your help is highly appreciated.
A good weekend to all.

Hi, I just do it the same and i think the problem is that you need a space character between the minus and the values.

Try with this expression : mod1.ale.minqual - 0.1

In my case, it is working. I did it in the following comsol model : www.comsol.fr/community/exchange/118/
