You have messed up your bounda

You have messed up your boundary conditions on the pressure and ve;ocity and the solver is blowing up on you. If you specify p on the boundary, you cannot specify U.

Just to make sure, run checkMesh on your case - if this does not report any errors, you need to look into 0/p and 0/U - that's where the problem is.

A bit unusual choice of momentum solver - why?

Hello, I am new to OpenFoam

Hello,
I am new to OpenFoam and am trying to test run a working solver for a new blockMeshdict file. I am learning as fast as possible to make my way around openFoam, but not sure where to go for debug help so specific. Any advice would be appreciated.
