<div dir="ltr">Hello Nek Users,
<div><br>
</div>
<div>I want to simulate low density jet (heated air whose density is lesser than ambient air) expanding out from a pipe into stagnant air.<br>
I want to run a 2D planar case. Im planning to export the mesh from exodus II to nek. Can somebody guide me what I have to do from here? What Stress formulation to use? Thanks for the help. <br clear="all">
