Hi,

I am trying to do Jozsef Nagy's christmas challenge from two years ago which was about calculating the flow around Blender's monkey Suzanne. I started as simple as possible using simpleFoam in laminar mode however for some reasons the result that I am getting looks very unphysical as you can see in the images of velocity magnitude and pressure. I also attached an image of the mesh.

What is causing this issue?

I would say I did nothing extraordinary in fvSchemes, fvSolution or controlDict. But if the problem might lay in one of those files I can attach them as well.

Thanks for your help!
