Could be use for this task laplacianFoam? How to set the boundary condition of the third kind (Robin boundary condition)?

But I have an idea how to use laplacianFoam in this task. Necessary to extrude the faces with three kinds of boundary conditions in a finite volume by the length (lambda / alfa), where lambda - the thermal conductivity of solid, alfa - heat transfer coefficient. Extruded faces to set the temperature of the liquid. On the lateral faces set zerogradient. I'll try to write a script to modify the mesh. Last edited by eugen2077; December 28, 2012 at 16:24.
