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
- 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.
- The shape truncation uses method from Homel et al, 2016
- The
CPDIrcrit
command is only allowed for MPM analyses.
