Condition for remeshing could not be evaluated !!

Please login with a confirmed email address before reporting spam

Dear All COMSELer's ;

I am trying to model a moving mesh problem, where an object is moving by a 5[m/s] velocity a way from another object. i used the sliding mesh Technic , where i created 2 unions and performed an assembly between them so i can get Identity boundary pair so the moving part can slide over it .
Now, the deformed mesh is relatively large 90[mm] which require adding Automatic remeshing , but as i add a condition i got this Error ;

The following feature has encountered a problem:
- Feature: Automatic Remeshing (sol1/t1/arDef)
Condition for remeshing could not be evaluated.

My remeshing condition is ;

sqrt(comp1.spatial.I1isoMax)>2

same as default , which is really weird !!
Any help ?!

Hi,
You maybe solve your problem, but if not try to change current conditions to lower value, from 2 to 1, or even 0.1. If it will not help try to check your movement function if it is precise, best add it as variable depend from time in time dependent solution.

You could also try change a function in Mesh Quality Expression from default one to new one depend not from material but from deformed geometry (ex. comp1.dg.minqual<0.1)

Hopefully one of those tips will help.

Cheers
