alikami Member ali Join Date: May 2009 Posts: 58 Rep Power: 17	Hi I am simulating gas-particle flow in conical nozzle. i performed 2 steps 1. converge solution for gas phase. 2. defined injection for particles (99) paticles Fluent says 78 escape.................22 incomplete... solution remains same even after a few thousabd iterations. Now when i check for DPM interaction , solution dont converge instead says reverse flow in inlet after a few iteration... i m using 300 iterations per DPM iteration 0.1 under relaxtion number of iteration 5000 step length 1 anybody help wats the problem Regards Ali
