Comments
 node_ID_{1}, node_ID_{2} and node_ID_{3} define the local coordinate system used for mapping.
Where, node_ID_{1} and node_ID_{2} define $X\text{'}$
node_ID_{1} and node_ID_{3} define $Y\text{'}$
 The coordinates of 2D data that will be mapped are defined in the local $X\text{'}$ and $Y\text{'}$ system using the /FUNC_2D X and Y input.
 When mapping scalar quantities such as density, pressure and energy, use /FUNC_2D with dim=1 and define the scalar value using Z1. For vector quantities such as velocity, use /FUNC_2D with dim=2 and define the vector using Z1 and Z2 (Figure 2 and Figure 3).
 If any inputs for veloctiy, volume fraction, density, energy, or pressure are constant, then the function can be left undefined and the constant values can be entered in the scale factor fields, Fscale_{v}, Fscale_{rhoi}, or Fscale_{p_e1}. If functions are defined, then the default value for the scale factors are 1.0.
 When form=VE, the model is initialized from density, specific internal energy and velocity. This formulation is available for all monomaterial ALE / EULER material laws and with material /MAT/LAW151 (MULTIFLUID) and /MAT/LAW51 (MULTIMAT).
 When form=VP, the model is initialized from density, pressure and velocity. This formulation is available for all monomaterial ALE / EULER material laws whose equation of state is provided through the /EOS card and with material /MAT/LAW151 and /MAT/LAW51 only if I_{form}= 12 is used.
 If explosive material LAW5 (JWL) is used as submaterial, then mapping will be proceeded considering all explosive was burnt (burn fraction = 1.0). The mapping will be done with detonation products only with a burn fraction = 1.0.
