I investigated that function is called in the updateInterfaceMatrix method of the cyclicFvPatchField. Going deeper,
the implementation of the call can be found in the cyclicLduInterfaceField::transformCoupleField
there the following code confuses me a bit
scalar forwardScale =
1. forwardT is a 3x3 tensor which defines a rotation ok
2. diag gives back the diagonal of the forwardT()
3. but what is forwardT() ?
4. pow is clear
5. why is that scale multiplied with a scalar
for (label facei=0; facei<sizeby2; facei++)
pnf[facei] *= forwardScale;
pnf[facei + sizeby2] *= reverseScale;
My explanation for that is that the forwardScale is a kind of jacobi
matrix because the pnf[facei] is a derivative or a sum of derivatives.
But i feel not good with that vague explanation.
So does anybody know what is going on in that part of OpenFOAM ??
And is there literature which explains what the forwardScale is?
Thank you for reading
