Hi,

I am testing dynamic mesh with layer addition/removal, so I crated a simple 2D case with moving car through a domain. Domain is composed of 2 cellzones (see the picture) and mesh modifier removes/adds cells only in the blue region. When I run the case in serial everything seems ok, but when I run it in parallel, solution crashes with the following error:

Quote:
Face 710 is active but its owner has been deleted. This is usually due to deleting cells without modifying exposed faces to be boundary faces.
After short investigation it turned out, that solution crashes when the extrusion faces in front of the car reach the processor boundary. You can see the domain decomposition in the atteched picture. I know I can avoid this error by leaving lower cellzone in one piece, but is there any other way?
