yes, you can write new turbulence model which is not supplied by fluent. first u need to write your governing equations and discretize the equations.. afterthat you have to write UDF for those equations and u need to hook those equations in FLUENT. suppose , if you want to write a turbulence model for low reynolds number k-epsilon model. for that u need to write UDFS for turbulent viscosity and k-source term and epsilon source term. after writing ur udfs, u have to hook these terms in appropriate places. think u undersand regards seeta

Thanks! I have went through the UDF manual recently, and saw many DEFINE macros. Could you suggest which one should I read first?
