Nodes sharing different type boundary faces
 

I am trying to solve flow inside a channel. Channel has one inlet and one outlet. The walls are treated as slip walls. It looks as if that solver can not treat for the nodes sharing different boundary markers (like inlet and wall or outlet and wall) correctly :(. I believe this is due to wrong surface normal treatment:confused:.
I am ready to share the mesh file with those who wants to discuss this issue. I previously developed a node based solver and I know that this issue is very critical.

Hi Mehmet Ali AK,

Would you please share the mesh file?

Best,
