ABQ_AM_MovingHeatSource_Uniform

You must include a parameter table of type “ABQ_AM_MovingHeatSource_Uniform” in the table collection for moving heat flux if the energy distribution type is set to “Uniform”. Parameters defined in this table indicate lengths, offsets, and subdivisions of the box toolpath used in the toolpath-mesh intersection module.

The parameter table “ABQ_AM_MovingHeatSource_Uniform” includes data that is used to define the geometric characteristics of the applied thermal load. One set of data defines the volume of the box (a rectangular cuboid) over which the applied volumetric flux (units of JT⁻¹L⁻³) is distributed. You define dimensions (lengths) of the box in the local ${\mathbf{x}}_1$ , ${\mathbf{y}}_1$ , and ${\mathbf{z}}_1$ directions (BoxLengthX, BoxLengthY, and BoxLengthZ respectively). The box dimensions you specify should be representative of the shape and size of the heat source. You also specify the number of subdivisions in each local direction of the box (SubDivX, SubDivY, and SubDivZ respectively). The full box is divided into a number of smaller boxes based upon the number of subdivisions you specify. The amount of volumetric flux applied to each smaller box is directly proportional to the ratio of the smaller box volume to the total box volume. For example, if you specify 4 subdivisions in each local direction, the full box will be divided into $(4\times 4\times 4)=16$ smaller boxes and the applied volumetric flux to each of the smaller boxes box will be $\frac{1}{16}$ of the total applied volumetric flux. Heat is only applied to elements that are intersected by the centroid of the smaller boxes. In general the more subdivisions you define, the more evenly the heat is distributed within your model, however the computational cost also increases. If you set the number of subdivisions in each direction to $0$ , Abaqus will automatically compute the number of subdivisions needed to make the volume of each small box equal to the characteristic element volume, which typically results in an acceptably smooth distribution of heat and reasonable computational performance.
