thiyam is on a distinguished road
Hi all, Please help
I am modelling gas-liquid interphase model in FLUENT. UDF for modified drag law is applied and successfully interpreted but the residuals are not converging (as i am considering 1e-03) especially for the gas phase,however the continuity equation is falling at 1e-06 when the simulation is running upto 7000th iteration. So, please suggest me for solving this problems.
