Comments
 The option can be used to initialize a 2D or 3D simulation from the results of a 1D simulation potentially obtained from an external solver.
 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.
 Three different initialization types are
available depending on the type parameter:
 type = 1: a planar initialization is performed where the 1D results are mapped onto a plane which is normal to the vector defined from node_ID_{1} to node_ID_{2}. The abscissa values in an input function are the distance along the plane’s normal vector. The ordinate values from the input function are a constant value for the entire plane at a given distance along the normal. See Figure 1 and Figure 2.
 type = 2: a cylindrical initialization is performed where the local z cylindrical axis is defined from node_ID_{1} to node_ID_{2}. The abscissa values in an input function are the radial distance from the local z cylindrical axis. The ordinate values from the input function are a constant value for the entire cylindrical surface at given radial distance. See Figure 3 and Figure 4.
 type = 3: a spherical initialization is performed, using the origin defined by node_ID_{1}. The abscissa values in an input function are the radial distance from origin. The ordinate values from the input function are a constant value for the entire spherical surface at given radial distance. See Figure 5 and Figure 6.
 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.
