Anqi H is still having a problem:
Hi Deepak,

I'm running the same simulation with icoFoam for 0.05s, the particles
are defined in fluidCouplingIDList and dynamic is disabled. The fluid
case without the particles converges in openFoam, but after the
particles are included, the simulation hangs after 0.01275s. I've been
having trouble understanding why the program hangs here as the courant
number is smaller than 0.5. The terminal output is copied to this post.
Another question is about inspecting p,U properties of the fluid cells,
since they are saved under two directories processor0,1, does it mean
paraFoam cannot be used in this case? Thank you.
