chtMultiRegionSimpleFoam - configuring solver
 

Hello everyone,

I am trying to work with a very simple case. I have 2D case with air flowing over a solid block. The bottom surface of the solid block is at 500K. I am trying to solve it with chtMultiRegionSimpleFoam. After configuring changeDicts and manually changing some of the boundary fields, my solver crashes with the error message attached.

I am also packing the case and attaching it with the post.

I tried to work with the classic planeWall2D case and port it to OF1606+. You can find it here: http://www.cfd-online.com/Forums/ope...penfoam-4.html

It sort of works, but I am not sure about the results. So I decided to create an even simpler case with just two domains.

I would highly appreciate any help on this!

Thank you in advance.
