Hi all,
i am currently working on particle laden air flow simulation inside a supersonic nozzle, it's exit mach number being 3using Fluent. when i start the simulation the solution is diverging and the error 'divergence detected in amg solver: pressure correction' is popping up which i couldn't understand why. i'm using discrete dense phase model and steady state tracking of particles. i've tried reducing all the under-relaxation factors. my mesh skew is below 0.98. i'm using phase coupled simple solver with first order discretisation for all. the volume fraction of the metal powder is 1%. i've double checked all my bondary conditions. does the error have anything to do with RAM sockets?. I read it somewhere. Any help is highly appreciated. Thanks in advance. |
