Detailed Description

A transformed field grid generator.

///////////////////////////////////////////////////////////////////

This generator transforms a given cylindrical grid by following the streamlines of a vector field \( \hat{ \vec b}\) for a set distance \(\Delta\varphi\) in the perpendicular direction. This only works by starting from a cylindrical grid
