Abstract
This code can be used to determine the effective heat conductivity of a thin periodic porous medium by solving a two- or three-dimensional local cell problem on pore scale using the software Netgen/NGSolve. The pore geometry of the representative cell and the boundary conditions on top and bottom can be set by the user. The same holds for the heat conductivities of fluid and grain as well as numerical parameters. All parameters are set in 'settings.py', together with four example set-ups that are already implemented there (for further instructions please refer to 'Notes'). If needed one can display or export the solutions of the cell problems in vtk-format.
