<p class=”MsoNormal”>Hello all, <\/p><p class=”MsoNormal”>I am reaching out for some help on a problem I am having with an Ansys Fluent CFD simulation I am running. I am trying to pump heat into an enclosure using a heater source but I believe my boundary conditions on the wall shadow of my heater itself are what are giving me the wrong renderings. <\/p><p class=”MsoNormal”>Attached below are some picture for reference. <\/p><p class=”MsoNormal”> <\/p><p class=”MsoNormal”><!– [if gte vml 1]><v:rect id=”Ink_x0020_23″ o:spid=”_x0000_s1030″
