boundary condition

      I am currently using Ansys fluent to analyze thermal convection in a 2D square cavity. If you select the bottom surface and set the temperature when setting the boundary conditions, the temperature of all the surfaces of the bottom surface will be uniform. I want to set boundary conditions only for a few points in the center of the bottom surface. Is there a way?n

      You'd need to break the surface up or use a profile. n

      thank you for your answer.nHow do you divide the surface?nAlso, please let me know if you like how to use the profile.n

      Do the CAD tutorials for the surface/edge divisions. nTry Google for the profiles, but the User Guide is pretty comprehensive. n

      File-> Export-> Profile-> Surface (bottom surface), Value (Temperature)-> Open this exported file in Excel, modify only the temperature part and save-> Boundary condition-> Profile-> Import-> Select the modified profilenI set the boundary conditions in the above procedure, but they were not reflected.nCould I ask the reasonn

      That's the process, what's not happening? n
