I'm currently running a rather large simulation in Star-CCM+ (LES, 8 mil.) and need to export results data for a great amount of timesteps and analyze it afterwards. Now my first attempt was to export it in the binary Fieldview (.fvuns) format (not really a conscious decision), only to find that neither TecPlot nor ParaView can read it and that the format is proprietary (thus I cannot write a reader for ParaView).

So before I waste more time experimenting around with the various formats, maybe someone can give me some experienced advice on which one to use. The only stringent requirement is that Star-CCM+ can export it, which limits the selection to

.ccm (the CD-adapco format),
.case (Ensight Gold),
.fvuns (Fieldview, to be avoided as mentioned),
.plt (Tecplot),
.cel/.sbd (Boundary Shell/Data files),
.ntl (RadTherm Patran Neutral),
.trn (Surface fft files).

Apart from that it would be nice if it was possible to

- selectively export the solution data and export the mesh data just once (since the mesh doesn't change)
- the data format is not restricted to saving values on either centroids or vertices
- the format is open source and versatile and under development.

Is there a much better format that is not in the list of formats that Star-CCM+ can export?
