ExactTractions Command

The ExactTractions command activates a mode where traction loads will be found by exactly integrating shape functions over the deformed particle edge:

ExactTractions <(option)>

where (option) is "yes" to activate the mode or anything else to not activate the mode. If (option) is omitted, it is assumed to be "yes".

Notes

  1. In theory, this approach is more accurate, especially at large deformations. In practice, it is difficult to confirm an improvement.
  2. This option only works for uGIMP and lCPDI shape functions and 2D simulations. If used in other simulations, an error will be reported.
  3. The ExactTractions command is only allowed for MPM analyses.
