Generalized Kershaw mesh transformation in 2D and 3D, see D. Kershaw, "Differencing of the diffusion equation in Lagrangian hydrodynamic codes", JCP, 39:375–395, 1981. The input mesh should be Cartesian nx x ny x nz with nx divisible by 6 and ny, nz divisible by 2. The parameters epsy and epsz must be in (0, 1]. Uniform mesh is recovered for epsy=epsz=1. The smooth parameter controls the transition between different layers.

Evaluate the vector coefficient in the element described by T at the point ip, storing the result in V.
Implements mfem::VectorCoefficient.

virtual void mfem::VectorCoefficient::Eval 
Evaluate the vector coefficient in the element described by T at the point ip, storing the result in V.
void mfem::VectorCoefficient::Eval 
Evaluate the vector coefficient in the element described by T at all points of ir, storing the result in M.
The dimensions of M are GetVDim() by ir.GetNPoints() and they must be set by the implementation of this method.
The general implementation provided by the base class (using the Eval method for one IntegrationPoint at a time) can be overloaded for more efficient implementation.
