particles suddenly vanish in a specific time step
I checked the output partfluid in paraview and the fluid particles vanish at time step t=1.9. when I check the run.out file there is a warning at t=1.9s where 50% of fluid particles are excluded. it also says 100000 DTs adjusted to DtMin (t:1.9896, nstep:70321).
How can I fix this issue?
articles of simulation (initial): 1344232
Particles of simulation (total)..: 4401780
DTs adjusted to DtMin............: 104666
Excluded particles...............: 3681119
Excluded particles due to RhopOut: 1991
P.S: In my previous tests, I have similar warnings but I did not have this problem with vanishing particles suddenly. In the current test, the geometry is changed a little.
