Hello everyone,
I am working on 2D problem with Multi-reference frame and when Iam trying to run my case Advancing DPM injections .... Injecting 80 particle parcels with mass 3.2e-23 at t = 0 Deleted 20 particles in injection pp1mm with total mass 8.000000e-24 kg Deleted 20 particles in injection pp0.15mm with total mass 1.600000e-23 kg Deleted 20 particles in injection np1mm with total mass 2.400000e-23 kg Deleted 20 particles in injection np0.15mm with total mass 3.200000e-23 kg Do you have any idea about this? ((I have four different injections in my case and the injection is from inlet.)) Am I missing something in setting any parameters for injection??????? |

Some say it is due to having a large mass flow at your injection.
I had the same problem, the mistake I was making was I had a zero velocity for the injecting particles  :Injection Point Proprieties => Velocity Magnitude |
