Inflow Particle Out

I am trying to use Infow and outflow to simulate the flow in the non-uniform pipe (input diameter > output diameter), but there seems to be errors regarding partiles out, what is the possible reason of this, is this due to my wrong configration (

attached the def file)?

Another question, can DSPH simulate high speed flow, e.g. flow at 2 Mach number?


  • Dear @James note that we will release new version 5 in 1-2 weeks.

    So please can you run the case again once we release this new version to check if the same errors still appear?
