How to get the particles trajectory from an Open Foam simulation

Sounds like this known problem with lagrangian data in openfoam.org version.

  • could use a different version (eg, OpenFOAM-v2006), which should be the same for your type of calculations.
  • could use the vtkCloud function object from openfoam.com, and attempt to port it to openfoam.org
  • foamToVTK to convert from OpenFOAM to VTK format
  • foamToEnsight to convert from OpenFOAM to EnSight format and then process that in ParaView.
