Hi, I have noticed somthing wrong with my export to OpenFOAM from the mesh software Pointwise. When I create a mesh, even the simplest one (a rectangle with inlet outlet and walls), the simulation crashes giving me the following :

Do you have the boundarys right?
You need two empty Boundarys in a 2D-Mesh. |

Can you explain me why I need two ? I based my simulation on the ones from the tutorials, I let the files in attached so you might be sure if that's the mistake I made (I'm quite new to OpenFOAM)

imho, not enough info to reproduce or understand the issue.

Renumber the mesh and it will run:
Code:
renumberMesh -constant -overwrite |
