CPDIrcrit Command

The CPDIrcrit command set a critical radius when using any CPDI shape function method

CPDIrcrit <(rcrit)>

where (rcrit) is critical particle radius in units of cell size.

Notes

  1. One problem with CPDI shape functions is that if a particle deforms too much, its' corners may extend beyond ghost rows into other patches used in parallel coding. If that becomes a problem, this parameter will restrict corner deformation to keep them within a single patch. Enter maximum allowed particle radius in units of cells.
  2. The shape truncation uses method from Homel et al, 2016
  3. The CPDIrcrit command is only allowed for MPM analyses.
