PtsPerElement Command

The PtsPerElement command selects the number of material points to use along each direction of each element of the MPM background grid under the defined body. Its format is

PtsPerElement (num)

where (num) is the number of material points per edge. This command currently allows 1 to 5 for 2D analysis and 1 to 3 for 3D analysis. The default is 2. The number of points per element will be square of this value for 2D and cube for 3D. In other words, will be 1, 4, 9, 16, or 25 for 2D and 1, 8, or 27 for 3D.

Notes

  1. The command must come before defining material points in your analysis. If desired, however you can use a different number of points per element in selected regions or when assigning particles using an image (but if you change it for selected regions, you are responsible for making sure particles do not overlap).
  2. The PtsPerElement command is only allowed for MPM analyses.
