This model works fine. However i was trying to see what if i do plain dispersion as in, the C1 gas just flows and based on density difference with air distributes itself in the domain. I put the Combustion model off (was using SCRS previously) and the radiation model off (IMMERSOL off), kept the energy equation, and solve for Pressure and Velocity on. For some reason when i try to run the solver absolutely nothing happens. It keeps on showing my objects in the pre processing window. I am not sure what i am missing. Any pointers would be of great help. Thanks in advance. Thanks Arnab Last edited by arnabchakrabarty; May 10, 2010 at 10:22.
