Detailed Description

This class implements a constant-Jacobian mapping defined by

\[ \bar{x} = \bar{x}(x,z) = x + f(z) \]

\[ \bar{y} = \bar{y}(y,z) = y + g(z) \]

\[ \bar{z} = z \]

where \((\bar{x},\bar{y},\bar{z})\) are the Cartesian (physical) coordinates and \((x,y,z)\) are the transformed (computational) coordinates.

This function initialises the Mapping object. It computes the coordinates and velocity coordinates, initialises the workspace variables, and calls UpdateGeomInfo, which will perform the calculations specific for each type of Mapping.

Parameters
pFieldsExpList array used in the mapping
pMappingxml element describing the mapping
