Maybe that is the problem. I just looked into the surface normal gradient schemes in OpenFOAM, and the coefficient psi should be 1 for corrected. I will look more into this and see if it changes my...

I am not sure if I have come across that while using snappyHexmesh. I am basically meshing the flow over a flat plate, so it is a fairly simple geometry. Is non-orthogonal correctors in the...

Hello Foamers. I am even more confused now. I made a new mesh with blockMesh and made sure the aspect ratios were 1:1. Used checkMesh, and all was well, however, when I ran my case again, the...

Thanks !!!! Well the solution is not right, when I compute for example the heat transfer scaling (LES of Wall Bounded Turbulent Natural Convection Flow), it is completely wrong. My simulations were...
