2D simulation of round jets
I have a question about how to simulation a 2D computational domain for axissymetric round jet. As you know, if I use two dimensional domain, how Openfoam can know it is a 2D case for round jet or for planar jet ?
In fluent, we can choose "axisymmetric" but I do know how Openfoam can distinguish this. Thank you so much if you can give me some suggestions.
This can be easily found in the User Guide. See e.g. section 5.2.2
