Hi Guys,<br><br><div></div>I had formulated the problem combining Navier Stokes with Energy Equation.<br>For that I wanted to try out Couette flow with pressure gradient (<i>plane Poiseuille flow</i>)
 with Thermal boundary conditions. For simple Couette Flow ( pressure 
gradient =0 ) the code is working fine and giving us the proper velocity
 profile but how to do it with user defined pressure gradient. <br>
See Link - <a href="http://www2.mech.kth.se/%7Eluca/Smak/rec5.pdf" target="_blank">http://www2.mech.kth.se/~luca/<wbr>Smak/rec5.pdf</a><br>which will give us velocity profile for this flow.<br>I tried imposing pressure boundary condition but it is not working out.<br>
I have attached the problem file. <br><div><br></div><div>Regards,<br></div>Ankit
