Hello everyone

I am running a coal combustion case in Fluent parallel with 6 nodes. It takes unusually long time for a single DPM iteration. For my case with around 2 million cells, it takes more than 2 hours for just one DPM iteration. And i have to use 50 continuum iterations per DPM iteration for good convergence. Is there any way to reduce this time. I am using Intel Xeon Quad-core processor (hyperthreading on)with 3.5 GHz frequency and 32 GB Ram. In another system with Intel i7 Quad core processor with same frequency and RAM, it takes about one half hour. Please suggest any way if possible to reduce the DPM iteration time.

Thanks
Saurav
