Rotation is applied across the first and second axes of the array. This rotation should be applied when one field is mapped onto the other. For example, a tracer indexed along u or v face points will map from one to the other after a quarter turn, and back onto itself after a half turn. mom_array_transform::rotate_array_pairrotate_array_pair_integer mom_array_transform::rotate_array_pairrotate_array_pair_real_2d mom_array_transform::rotate_array_pairrotate_array_pair_real_3d
