Comments

  1. 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.
  2. 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_ID1 to node_ID2. 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_ID1 to node_ID2. 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_ID1. 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.
  3. 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.
