By default, a wall will have a thickness of zero; however, by specifying a non-zero wall thickness, a thin layer of material can be modeled on the wall. The thermal resistance of the thin wall is determined by the specified Wall Thickness, as well as the selected material in the Material Name drop down menu. This ‘Thin Wall’ feature can be used to model, for example, a thin piece of sheet metal between two fluid regions, a coating applied over a solid, or modelling contact resistance between two solid regions. Please refer to the attached PDF file for information on applying thermal boundary conditions to thin walls.
