I am new to OF, I am trying SymmetryPlane BC on my topWall rather than zerogradient.

Here is the error (below), anybody knows what I am doing wrong ? Thank you


patch type 'wall' not constraint type 'symmetryPlane'
for patch topWall of field U in file "/..../channel402/0/U"

file: /work/a/ahafsi/channel402/0/U::boundaryField::topWall from line 31 to line 31.

From function symmetryFvPatchField<Type>::symmetryFvPatchField
const fvPatch& p,
const Field<Type>& field,
const dictionary& dict

in file fields/fvPatchFields/constraint/symmetry/symmetryFvPatchField.C at line 99.

Hi Amin,

It seems that you specify wall patch for topWall in blockMeshDict, then you can not specify symmetryPlane to that patch again. In your blockMeshDict, you might want to use something like "patch topWall {..}" instead of "wall topWall {...}".
