Comments

1. node_ID₁, node_ID₂ and node_ID₃ define the local coordinate system used for mapping.

   Where, node_ID₁ amd node_ID₂ define $X\text{'}$

   node_ID₁ and node_ID₃ define $Y"$

   • $Z\text{'}=X\text{'}\Lambda Y"$
   • $Y\text{'}=Z^{\prime }\Lambda X^{\prime }$

   
   
   Figure 1. Moving System with Dir=X

   $Y\text{'}$ is the axis of symmetry for the 3D axi-symmetric mapped data.

2. 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.
3. 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 3 and Figure 4).
4. When form=VE, the model is initialized from density, specific internal energy and velocity. This formulation is available for all mono-material ALE / EULER material laws and with material /MAT/LAW151 (MULTIFLUID) when only one sub-material is present.
5. When form=VP, the model is initialized from density, pressure and velocity. This formulation is available for all mono-material ALE / EULER material laws whose equation of state is provided through the /EOS card and with material /MAT/LAW151 when only one sub-material is present.
