Domain not remeshing
 

Hi all,

I defined a circular shape in a square domain meshed with triangular elements. Now the circular shape is rotating and translating in the square domain (defined using a cg_motion udf, with sinusoidal shape) and I want the grid to be remeshed as soon as the skewness exceeds 0.7 (I also turn on smoothing for the deformation when no remeshing is needed). When I apply the relevant setting in "dynamic mesh" tab and preview the mesh motion, the smooting occurs but no remeshing is taking place even if the max skewness clearly exceeds 0.7. (local cell option is enabled btw)

Anyone suggestions on what might be wrong or where I am defining something wrong?

Additional information
 

In attachment you can see the domain, the inner domain oscillates in the domain (translate and rotates) but the outer domain becomes very skew after a few iterations so I want to apply remeshing but this is not doing anything ... the remeshing does not seem to "turn on".

Hi adubois,

I have the exact same problem, have you had any succes in fixing it ?

Yes I have, you should only add the moving boundaries as dynamic mesh zones and not the actual "zones" that should be remeshed (is counter intuitive I know). Is it working now?

Yes ! it works perfectly now, i would have never found that myself! thank you so much ! strange though !

No problem man, I was a hunch that made me try that and it worked! If I can help with anything else let me know
