A body can be defined by creating a Material Point within a closed volume. Material Points can be created at a specified point or at the centroid of two points.
In the example geometry shown in Figure 199: Creating Material Point, the material point is specified at the centroid of the cube, therefore the body will be defined as the inner cube. A volume mesh generated for the body will fill the inner cube as shown in Figure 200: Volume Mesh of Defined Body.
