Hi all,
The rotational transformation tensors in transform.H seem to be the transpose of the actual transformation tensors. For example: Code:
//- Rotational transformation tensor about the z-axis by omega radians inline tensor Rz(const scalar& omega) { const scalar s = sin(omega); const scalar c = cos(omega); return tensor ( c, s, 0, -s, c, 0, 0, 0, 1 ); } I checked multiple versions of OpenFoam and they all do the same thing. Why is this? |
