It might be very easy questions 1)Which solver is best segregated solver or coupled solver in Fluent 2)Where do I specify the equivalence ratio in premixed combustion model in Fluent. 3)How can I include my new additional terms in k or epsilon equation when I use k-epsilon turbulence model.

out of these I got answers of for one

Equivalence ratio os not specifed when you simulate premixed combustion it is assumed to be one.

I am trying to use RST model for turbulence but when I start my calcuation the residual started to increase to 100 something like that.

Anybody know what is the problem where I am doing some mistake. bob
