Dear All,

I'm trying to understand the slip boundary condition.

I don't understand the meaning of the transfomation
(|n_x|,|n_y|,|n_z|) in snGradTransformDiag

vectorField nHat = this->patch().nf();
vectorField diag(nHat.size()); 
diag.replace(vector::X, mag(nHat.component(vector::X))); 
diag.replace(vector::Y, mag(nHat.component(vector::Y))); 
diag.replace(vector::Z, mag(nHat.component(vector::Z)));

It is used in the valueInternalCoeffs, valueBoundaryCoeffs (and the respective gradient variant) of the transformFvPatch.



Thanks.
