You must include a parameter table of type “ABQ_AM_MovingHeatSource_Goldak” in the table collection for moving heat source if the energy distribution type is set to “Goldak”. Parameters defined in this table indicate parameters used in the Goldak expression of laser energy distribution (see Figure 3 in Thermomechanical Analysis of Powder Bed–Type Additive Manufacturing Processes Using the Trajectory-Based Method). It is assumed that material is deposited below the laser path defined by the event series; therefore, you must choose “Below” as the deposition position in the table of type "ABQ_AM_MaterialDeposition_Bead" for a bead-type material deposition method.
