Mesh Interfaces not showing - Cooling Plate
2 Attachment(s)
Hi all,
I have a problem with the mesh interfaces on fluent. I want to model a cooling plate with a straight cooling channel with a liquid coolant. I have uploaded a screenshot of my cooling plate within ANSYS Fluent. As you can see from there the "Mesh Interfaces" command is not there. This command should be in the tree on the left - see other screenshot. I need to set the mesh interfaces to enable the coupled wall option so that the heat can be transfered correctly. I believe that this problem may be caused by my original geometry. Does anyone has any suggestions on how to solve this? How can I modify the settings in order to show the mesh interfaces command in the tree on the left? Thanks! Tom PS: I have already tried to create a manual contact region in the design modeler. |
You don't see interfaces because of your mesh, because of the way, you'd generated it.
If you are using design modeler than it looks like you put all created bodies into one part so the fluent detected one body with different zones inside. so if you want to have interfaces, just put bodies into different parts. But for your case -> conjugate heat transfer from fluid to solid, your mesh is correct, you don't need to use interfaces in such simple case. (usually interfaces are been using in cases where it is really difficult (expensive) to make conform mesh) So you have 2 zones solid and fluid. Fluent will generate coupled boundary condition between them automatically! (it will have the same name with word shaodw at the end, for instance "channel_wall" and "channel_wall_shadow") best regards |

Thanks for the reply. I followed your advice for simple geometries and didn't create any interfaces. However, no shadow walls were automatically created by fluent (In this case I haven't created any contact regions between the fluid domain and the plate). I proceeded with the transient simulation anyway by enabling the energy equation. Setting the inlet velocity to 1 m/s, inlet temperature to 250K while the plate temperature to 300K. I am uploading my results here. No heat transfer seems to happen between the solid and the fluid. Is there something else I should do when setting-up the simulation prior to running it? Thank you in advance. |
