refineMesh globalCoeffs questions
 

Does the xyz coordinates systems in refineMeshDict correspond to the x1x2x3 coordinate system that we define in blockMesh ?

My mesh is a box containing only hexes, x1x2x3 coords are defined by the order of my vertices in blockMeshDict. If I want to refine with the same coordinate system as defined in blockMeshDict, do I need to change tan1(1 0 0) and tan2(0 1 0) ?
