}When parameter artTransform is on, the velocity components are of axial radial and tangential meaning. Otherwise, the velocity components are always Cartesian.
The inlet patch is virtually divided in to number of intervals. When parameter r is prescribed (with e.g. five height levels), the inlet patch is virtually divided into five radial intervals. Into each interval is prescribed corresponding value (linear interpolation is employed here).
