And yeah, when I made the forum post the images were way bigger, so I&#8217;ll keep that in mind next time. The base of the geometry was given in the dissertation I was following. The only part I changed was that the primary and secondary inlets now enter a complete chamber and the fact that the domain is now 3D instead of 2D axisymmetric. As far as using the PBCS solver, I&#8217;ve tried that and it does work considerably better. But from everything I&#8217;ve read regarding gas ejector CFD the density-based solver is what everyone runs with, so that&#8217;s why I was using it. As far as why the domain has to be 3D, I&#8217;m wanting to eventually include a third inlet to the starting chamber. I have a task involving the mixing of certain gas species using the ejector, and some of those species are to enter through a third inlet, which will have its own temperature and pressure conditions. When using the PBSC solver, what would you recommend regarding the settings for Discretizations schemes, URFs, and the Time Scale Factor for good convergence?&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-397314","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Thanks for the reply!
