Hello folks.

I am working with dynamic meshing and due to instabilities from the coupled calculation of flow field and rigid solid motion calculation using UDF, I have to use implicit mesh update to achieve stability.

The big issue is that using implicit mesh update, calculation process of each time step became very time consuming, my beard is growing a lot.

Implicit mesh update can only be "restricted" to be called in every iteration of the time-step using a frequency within the time step iterations (For example every 10 interations)

What I need is to update the mesh during the first iterations and not during the complete time-step iterations. For example, first 20 iterations of the time step.

Thanks for your help.

Regards


Alberto
