Both MPM and FEA calculations can do 2D or axisymmetric calculations. MPM can additionally do 3D calculations. You pick the type of analysis to run with an analysis command. In command scripts, the format is
Analysis (number or name)
In XML files it is
<Analysis>number</Analysis>
Analysis Options
The possible analysis types, by number or name to use in above commands, are:
- 0 = "Plane Strain" for a 2D plane strain FEA analysis
- 1 = "Plane stress" for a 2D plane stress FEA analysis
- 2 = "Axisymmetric" for an Axisymmetric FEA analysis
- 10 = "Plane Strain MPM" for 2D plane strain dynamic MPM analysis
- 11 = "Plane Stress MPM" or 2D plane stress dynamic MPM analysis
- 12 = "3D MPM" or 3D dynamic MPM analysis
- 13 = "Axisymmetric MPM" for axisymmetric dynamic MPM analysis
When using analysis name in scripts, it must exactly match the quoted text above (case insensitive).
Notes
- The first three (0,1,2) are for FEA calculations only, while the rest (10,11,12,13) or for MPM calculations only.
- In axisymmetric analyses, the x, y, z, directions become R, Z, and θ directions. If any commands do not mention use of R and Z, they may still work or you can use x and y to mean the same thing. When visualizing results, most labels are changed to reflect R, Z, and θ coordinates. The implementation of axisymmetric MPM is described in a paper by Nairn and Guilkey.[1]
- One (and only one) Analysis command is required in every input file.
