ParticleBC Command

Forces, tractions, or fluxes are applied to particles in MPM calculations using a series of ParticleBC each. Each block selects some particle using one suborinate shape command. LoadType Commands within the structure can determine whether the Load Commands specify particle loads or total load on all particles in the current shape. The format for the block is

ParticleBC
  (one shape command, which can be nested)
  (any number LoadType and Load commands)
  (any number of Traction and/or HeatFlux commands)
  (any number of ConcentrationFlux or  PorePressureFlux commands)
  (any number Damage commands)
EndLoadLIne

All particles within the one shape can be assigned to LoadType, Traction, HeatFlux, ConcentrationFlux, PorePressureFlux, or Damage conditions by using commands between ParticleBC and EndParticleBC

Notes

  1. Use only 2D shapes or 3D shapes for 2D or 3D simulations, respectively.
  2. These shape commands are only allowed for MPM analyses.
