Hello,

I am running a simple simulation of flow between two plates within OpenFOAM and comparing the results from both blockMesh (BM) and Pointwise (PW) meshes. I've successfully run simulations for each, however, the results from the PW mesh are inconsistent with the BM (and effectively theoretical), even with identical case files and mesh dimensions.

I have only just started using PW, and I expect there might be an error in my setup, but I followed online tutorial instructions.


Here are the issues I am seeing from the PW results:

-Number of iterations for Ux and Uy are constant at 1000 throughout simulation. (compared to 4, 3 ... 0 for BM)
-residuals level off at 1e-3, when specified to be 1e-6 (see attached)
-Velocity profile is not symmetric about the centerline (see attached where centerline is at y=.013)

Ultimately I'm looking for help on the Pointwise to OpenFOAM process.

Thanks
