Good morning all,
i am a mathematics research scholar , i need some results in rayleigh benard convection for a square cavity or 3d cavity just for comparison. the fluid consideration is air or water. for air i tried the following transport properties // Laminar kinematic viscosity nu nu [0 2 -1 0 0 0 0] 1.000000e-03; // Thermal expansion coefficient beta beta [0 0 0 -1 0 0 0] 1.019368e-03; // Reference temperature TRef TRef [0 0 0 1 0 0 0] 290; // Laminar Prandtl number Pr Pr [0 0 0 0 0 0 0] 0.7; //1.0000e+01; // Turbulent Prandtl number Prt Prt [0 0 0 0 0 0 0] 0.9; delta T=1 but i could not get steady state. Can anyone help me to get steady state ? |

Hi, your case is done? And I wonder which solver in OpenFoam is used for this convection simulation?

I am doing simulation for Natural convection using buoyantBoussinesqSimpleFoam and i got some results, please tell me how to plot Residual plots, pyFoamPlotRunner.py is not working ? can we use paraview to see Residual plots ? to find Nusselt number please tell me how to find derivative with respect to x and y in paraview ?

Would you mind to show your results if it does not bother you? And you want to show Residual or Nusselt plots?
