Skew Coordinate System
A skew coordinate system is a system of curvilinear coordinates in which each family of surfaces intersects the others at angles other than right angles.
Skew coordinate systems do not allow separation of variables and so are not commonly encountered (e.g., Moon and Spencer 1998, p. 1).
