Hi guys,

I'm new to Fluent. Now I'm doing a gas leaking model however the energy cannot converge after about 40 iterations. At the beginning, energy residuals decreased and after 10 to 20 iterations it increased.
I don't need to solve for temperature but the energy equation comes with the species transport model. Is there any possible way to solve this problem? Any advice is appreciated.
Models involved are energy, laminar and species transport. 300K was signed to the velocity-inlet face and same T for all faces where applicable.

Thanks a lot!
