30. SPH Flood 620.000 particles
10 months ago
This is a little scene Grant modeled and then I tweaked the parameters on the fluids, to find a good balance for this kinda of scene.
Interesting thing about the emission... The particles get emitted inside of that tube, but the tube is kinda of "small" for the number of particles that the emitter is putting out, so the pressure increases inside of the tube and the particles go away not just with gravity but also with the increasing pressure that's created inside of the emission container.
620.000+ particles
12 substeps

Thanks man! This example is hard to reproduce on realflow with stability.
-T
it's a dual quad (an old one) with 8gb ram, the memory didn't go that high for this sim but I'm on a 64bit.
Simulation time, it's 12 substeps, with 50.000 particles a second. So it's 1600 more particles per frame.
Looking by the cache files
first 30 frames ~ 10min
30 to 60 frames ~ +37min
then +1 hour
then +1.5 hour ~ 206.874 particles..
in the end with 600.000 particles it was making one frame every 10 minutes... so it get's quite slow there.
However, you would have to use 100 substeps or more to get this it stable in Realflow... so I'm not sure how slow this is compared to other SPH solvers.
But I do know we can get ours much faster... hold on :)
