Dear Nitish,<br>
<br>
<br>
There are several examples of Rayleigh-Benard convection that show how to do buoyancy driven flows. Looking at those usr files would be a first step.<br>

Subject: [Nek5000-users] Low-Density jet using low -Mach number formulation<br>
<br>
Hello Nek Users,<br>
<br>
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>
