    Automatic and Manual Meshing

      I am running a simulation to predict the heat flux on the floor.

       

      At first, I tried with the automatic meshing with a level of 6 but this takes time. Then later on, I switch on the manual meshing and it gives me the number of cells in X, Y, and Z. This will take less time.I have run both cases. The results are nearly similar.

       

      However, I am not sure about the manual meshing becuase there is curvature refinement, refing cell, narrow cells. I don't know if I need to tune these.

       

      Please could you clarify this and how do I know that the manual meshing is working fine and I am in the right direction.

       

      Regards

          If you are meshing flat parts, you can use a draft quality mesh option, which will reduce the number of degrees of the mesh

              Where could I find the draft qualtiy mesh?

               

              The sold model that I have is a 70 Ft tube lenght surrounding by a cover. The hot gas flow inside the tube and emit radiant heat to the floor. I have a heat source at the beginning of the tube with a fixed firing rate.. The goal to obtain net radiant heat on the floor.

               

              Could you advise what is the best way to mesh "Automatic versus manual". Also how to obtain from the simulation the part of the heat lost as a convective heat
