I am using Gambit and Fluent for the modeling and simulation (3-D) of a gaseous jet discharging from a circular pipe into a rectangular duct with crossflow. I would like to know, how to mesh such geometry (pipe normal to a rectangular duct) in Gambit.

Thanks a lot Maged

Dear Friend:

You have better to use non-conformal mesh for this case. But if detect ralative dimension of duct and inlet pipe I can give you more exact offer. However, you can develop a structured hexahedral mesh, during an acceptable mesh constructing time, for this problem.
