I will think on whether the 2D step is necessary then.<br \/>\n<img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/444\/CDCG6GYBDP1T.png\" width=\"503\" height=\"410\" \/>Here is an annotated diagram of my simulation. Air enters at the inlet (in blue) and exits through the slit outlet (in red). The turbulence model is Transition SST. The inlet velocity is known and the goal of the simulation is to monitor the velocity field at the outlet<br \/>\nMy primary trouble with setting up the simulation is defining the outlet. When setting up the named selections in the meshing step, i don&#8217;t know <strong>how to define the slit gap as the outlet<\/strong>. Selecting the surrounding edges did not work. Could you shed some light on how a gap could be defined as an outlet?<br \/>\nThanks again.<\/p>\n","protected":false},"template":"","class_list":["post-206020","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/206020","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/206020\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=206020"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
