Notable Changes

  • Added reference implementation of the multi-level coarse-grain (MLCG) model of the DEM, including
  • fix ave/euler/region to measure Eulerian properties in a region made up of hex-cells,
  • fix forcecontrol/region that implements a PID controller using data from 2 fix ave/euler/region commands as input,
  • fix massflow/mesh/face to measure mass flow through a surface mesh per cell,
  • fix insert/pack/face to insert particles in a hex-region based on data from fix massflow/mesh/face,
  • region mesh/hex for loading and searching hex-cell regions

(plus their multi-partition counterparts fix ave/euler/region/universe, fix forcecontrol/region/universe, fix massflow/mesh/face/universe, fix insert/pack/face/universe; additionally, some quality of life features have been added, e.g. extract_surface, extrude_surface )

  • Added option set_property to fix insert/* to set a value for a property/atom upon insertion (ported from LIGGGHTS-PUBLIC)
  • Added option implicit_integration to fix nve/sphere / fix couple/cfd/force/implicit
  • Added option ave_euler to dump euler/vtk to specify a certain fix of type ave/euler/* if more than one is used
  • Added option cell_center to dump euler/vtk to indicate whether cell centers or complete cell shape should be dumped
  • Added option cell_data to fix mesh/surface to load additional cell data from VTK mesh files
  • Added option starttime / endtime to fix print
