Fluent wall thermal
Web1. If you are modeling the fluid side only, you do not need to do anything to have an adiabatic condition. If you are modeling the wall, the heat transfer coefficient will be computed and not an input at the interface of the fluid/solid. 2. The thermal conductivity can be inputted without using a UDF in a number of ways. WebOct 3, 2024 · Import the case file exported from the meshing software to Fluent. You can edit the wall boundary condition in Fluent and change thermal condition to "Couple" for fluid solid interface which you ...
