Hello

I get the following error when I use cyclic boundaries with dynamic mesh.

Selected 2080 cells for refinement out of 100000.

If you are certain your matching is correct you can increase the 'matchTolerance' setting in the patch dictionary in the boundary file. 
 Rerun with cyclic debug flag set for more information.

Any ideas on how to fix this?

Hi aliyah,

I have run into the same problem. Using cyclicAMI seems to work with dynamic mesh refinement, but not cyclic.
It seems the cyclic 1-1 coupling is not possible with dynamic mesh refinement (yet).

I think the foundation version has a new cyclic boundary condition that might work with dynamic mesh refinement.

Hi torjo

yes, when I change it to the cyclicAMI it is working. Thanks

Best,
