hi i have a converged solution of heat transfer through different fluid and solid.but in have not correctly solved energy equations in the solutions.can anybody help me

Please try to change:

Define->models->solver->gradient option to Green-Gauss node based Or Least Squares cell based

Do you solve system with or without chemical reaction? Which version of Fluent do you use?

best regards Nicoslaw

yes i have already node based and i am not using chemical reaction and my fluent is 6.2 . i have another question for complete solution of energy equations i solved energy and flow equations sepraetly alongwith turbulence. can you tell me that whether it is preferable to solve flow equation first than energy equation
