Hi all, OpenFoam rookie here.

I am currently trying to model spray droplets around a Rotorod air sampling collector. the Rotorod rotates at 2400 RPM and I have already modeled it using pimpleFoam but I have not captured enough time to complete a particle tracking study due to how computationally expensive it is. I am currently planning on duplicating the flow field files that cover a full rotation of the Rotorod (which are in steady-state) over enough time to complete the study but this method will take up northwards of 600 GB of storage with just the velocity field/moving mesh data.

Is it possible to set up a lagrangian solver like icoUncoupledKinematicParcelDyMFoam to read the velocity field of the Rotorod rotating once on loop? This would make my life a lot easier

Cheers,
Reid
