Sounds like this known problem with [lagrangian data in openfoam.org version](https://discourse.paraview.org/t/paraview-unable-to-read-lagrangian-data-openfoam/3456).

- 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](http://openfoam.com), and attempt to port it to [openfoam.org](http://openfoam.org)
- foamToVTK to convert from OpenFOAM to VTK format
- foamToEnsight to convert from OpenFOAM to EnSight format and then process that in ParaView.
