Hello, nThanks for the details. I do see that you have used the Local Zone Scale Info and that is good to have. nDid you try to preview the mesh motion and does it fail during the preview itself?nCan you also try to split your domains in such a way that you could use a Layering approach on the piston side?nSplitting can also help in reducing the region where remeshing is actually applied. nAlso is the can you test by reducing the crank speed to see if it goes through?.Regards,nSuryann
