Analysis Command

The one Analysis command allowed in each input file is used to set the FEA or MPM analysis type and optionally to set the default element type. This command should come at the beginning and before any command that needs to know if the analysis is FEA or MPM. Its format is:

Analysis (type),<(elem)>

where (type) is the analysis type to do:

The (elem) parameter is an optional element type (see Element Command for details; the element can be specified in the Analysis command or in a subsequent Element Command).

Notes

  1. Simulations with particle spin are only allowed in OSParticulas and then only if that code is compiled with particle spin feature activated.
  2. 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 axisymnmetric implementation here is described in a paper by Nairn and Guilkey (2013)
  3. A feature in development can generalize MPM plane stress or plane strain to allow non-zero, out-of-plane strain or stress, respectively. The only way to set out-of-plane stress or strain is to use a PropertyRamp custom tasks. More information and list of materials that support this option are on OSUPdocs.
