Summary0001785: Particle in LPT solver dissapear after they got accelerated in MRF
DescriptionSolver: simpleReactingParcelFoam with MRF

I am simulating a particle flow through a dynamic geometry (fan blade in MRF).
Small particles (1x10⁻6 m) disappear after they got accelerated due to the rotating motion of my geometry.

The particles get through my geometry when I enable the rotating option (fvOption) or when I increase the diameter to 1x10⁻3 m (with rotating). As forces I am using sphereDrag and gravity.

Is this an OpenFoam bug that the small particles disappear or is something missing in my setup?
Additional InformationI had the same problems with previous versions (2.3.0 and 2.3.1).

The particle velocity before they disappear is around 250 m/s and the particle diameter is 1e-06 1-e5

No further feedback, possibly resolved by new barycentric tracking:
