Problem in Ansys Fluent, Macroscopic Particle model(MPM)

Achini · July 21, 2020, 11:35

Hello!
I'm trying to simulate a cinematographic separation using MPM(Macroscopic particle model) in Ansys fluent (2020 student version).

I have created a particle injection at the inlet of the channel and i'm using "particle track" option to tract the flow of the injected particle.

The problem is, when i run the simulation, the injected particles do not appear.
Can someone help me with this please?
Thank you!

Did you manage to figure out what the issue was? I am having the same problem myself, in nothing happens when I click on 'display injection'. The only issue I can think of is that in the only tutorial I could find (on Youtube by a company called Difotech), they created some kind of ASCII file in the 'write particle data' section'. I am not sure if such a file is needed to allow initialization. However, I am not sure what kind of information this file needs to contain. If you did find the issue, could you please contact me?
