i am analysing the jet from nozzle,i created cuboid as a domain. I gave all sides as pr_far condition.Is it crrect?.then i want fine mesh near the nozzle exit in the form of conical shape and far field i need coarse mesh. how to do this type of mesh. please reply me

Hi,

Instead of fine mesh in the geometry try adaptive grid techinque and select some area behind the nozzle where u r interested.
