hello,

i tried to modell rice, flowing out of an hopper. the modelling works fine and the results looks the same as my high speed camera video of this real experiment.

While analysing the results, I get some noise. The plot shows the fill height dirung the rice flowing out of the hopper. These simulation runs done with the same initialization. I guess this is the numerically inaccuracy  while solving the differential equation. is there any option to reduce this error, except for running replications?
