[DesignModeler] Extend fluid volume 3D nozzle -- CFD Online Discussion Forums

June 10, 2015, 08:16	Extend fluid volume 3D nozzle	#1
Engineer1 New Member Jacopo Join Date: Jun 2015 Posts: 10 Rep Power: 10	Hi, I have a 3D nozzle (imported from a CAD) with BCs of pressure outlet, so I decided to extend the volume domain to avoid reverse flow at the outlet. Since I am new in fluent, I am not very experienced with this practise.. What is the best way to do that? I mean, can I create it in designModeler or must I do it in my CAD software? should I do boolean operations on the two volumes before meshing? and where should I impose the boundary condition of pressure outlet? Thanks in advance
