  I am dealing with Rayleigh-Benard convection problem inside a square cavity, in which bottom plate is heated & top plate is cooled, while the side walls are adiabatic. I was trying to get temperature gradient (dt/dy) option for the hot plate as well as cold plate. I searched a lot, but did not get that option in solver. can anyone please help.n

  nResults xy plot ... from the boxes on the left check one on the position ... then from the drop down menu, select gradients ... n

  I have checked in the results section of xy plot, there is option for derivatives (gradients), but in drop down list of derivatives there are only three options, dp/dx, dp/dy & dp/dt.nNo temperature gradient options are there.n

  Hello, nYou will need to keep the temporary solver memory from being freed in pressure based solver to display the temperature and other gradients apart from the basic one.nPlease use the TUI command /solve/set/expert and then say yes for Keep temporary solver memory from being freed? option. nYou should then be able to visualize the temperature derivatives.nRegards,nSDn

  Thank you very much Mr. Sdeb, your answer worked for me. n
