Summary

User subroutines are built as Dynamic Link Libraries (DLL files for Windows) or shared objects (.so files for UNIX platforms). The shared libraries are then linked with CFD-ACE-SOLVER such that a two way communication between the solver and the user defined input is established. 

Details

CFD-ACE+ provides eight user subroutines to control the shape, initial conditions and motion of macroparticles:

  • umacrop_init
  • upblock_bforce
  • upblock_pforce
  • upblock_vforce
  • upblockage
  • upmotion
  • upoint_init
  • upoint_xyz

An example for each of them is provided in this demo.
