Quick start
To run the model, open brick.pro with Gmsh
and click on the "Run" button in the left panel.
Features addressed in this tutorial
- Contact thermal resistance (idealized thin region with high thermal conductivity)
- Thermal electrode (floating temperature in a region of high thermal conductivity)
- Computation of heat flux through surfaces
- Import of a source field from a file
Additional information
This model is a rectangular brick with two windows, where various kinds of thermal constraints can be set. Dirichlet, Neumann and convection boundary conditions are imposed on different parts of the surface of the brick. The model is rather academic but it demonstrates some useful high-level GetDP features.
The floating potential idea (introduced in tutorial 4) is reconsidered here in a thermal context to represent a region with a very large thermal conductivity where, consequently, the temperature field is uniform (exactly like the electric potential is uniform on an electrode).
