Grid independent solution
 

Hi,

Is it better to refine the mesh in gambit and try to get an grid independent solution ? ------------ or --------------- Is it necessary to use grid adaptation in Fluent to check grid independence?

Which one of the above two give a better solution? Does it depend upon the type of problem one is trying to solve?

I am studying a laminar flow in a pipe intersection.

I would be thankful if anyone can help me with my questions.

Regards, Suresh
