Hello everyone,
I am running an unsteady DPM model in ANSYS and everything was going great until recently i got the following msg: WARNING: 0.0002% of the total discrete phase mass were behind in time by, on mass-weighted average, 0.000481 s, which is 0.0382% of their total age or 96.2593% of the last time step It is reallyyyy slowing down my simulations. One day to do just 20 iterations I set the fluid flow time step the same as the particle time step which is 0.0005 seconds. Max number of time steps = 10^9 Max number of continuous phase iterations per DPM iterations = 1000 step length factor = 0.001 iterations per time step = 300 |
