hello ! Please how modeling cold flow in liquid fuel and air(C5H12-Air), how to tell to fluent there is no flame ???

Hi

You can switch off the volumetric reaction in the species reactions panel, and you'll have to switch off the species calculation in the solution controls panel as well.

Steve

ok but how about species transport panel ??? should I define only the reactants as species ???( CH4,N2,O2) ???

thanks

Hello

I'm not really sure exactly what you mean by define 'only' the reactants as species. If you're using the species transport model then your reactants and products are defined as species.
