Hi all. A CFX and Fluent user having a go at OpenFOAM, and currently making a right hash of it!


OK, simply put, I'm trying to take the existing simpleFoam tutorial pitzDaily and use it on a different mesh (a NACA0012) to get me started. However, I keep getting the following error:

incompatible dimensions for operation

[U[0 1 -2 0 0 0 0] ] == [-grad(p)[0 -3 -2 0 0 0 0] ]


From function checkMethod(const fvMatrix<Type>&, const GeometricField<Type, fvPatchField, volMesh>&)
in file ..\..\src\finiteVolume\lnInclude/..\fvMatrices\fvMatrix\/fvMatrix.C at line 1208.


Obviously, I assumed it was inconsistent dimensions on by "boundary" files within the /0/ folder, however, the dimensions are correct, and are exactly the same as within the OpenFOAM tutorial folder.

After which, I have tried to check whether my mesh is at fault, but checkMesh comes back ok - but I suppose it will not be checking my boundary file within /constant/. I've tried various different mesh, including those available from Polito* for use with AeroFoam - modified for simpleFoam usage, with no success.

Anyone any ideas? Even just of where exactly I am being stupid!
