 August 29, 2007, 02:18 Hallo! I am a new OpenFoam- #1 New Member   Michael Krobath Join Date: Mar 2009 Location: Styria, Austria Posts: 2 Rep Power: 0 Hallo! I am a new OpenFoam-User and just doing my first steps. Beside some other things I need to calculate the temperature distribution in a solid block, which consists of some different materials. The thermal conductivity of these materials depend on the temperature. Boundary conditions are mostly a temperature, a heat transfer coeffizient/ambient temperatur or heat flux. I would need the temperature in steady and unsteady state. Up to now, I used Fluent/Gambit for those problems but in future we won't. Creation of the mesh is no problem. But how can I setup this problem in OpenFoam? Do you know any tutorial or test case, which I can work thru to learn, how to solve such a problem? Thanks in advance Michael

Cheers! Prashant

As I understand it, he doesn't need the fluid part (except for the boundary conditions) - all parts are solid. So on one hand that solver would be too complex, on the other hand it is too simple because it still uses a constant thermal conductivity. The "simplest" way would be to modify laplacianFoam to use a field instead of a constant for the "diffusion coefficient"/thermal conductivity.

 August 29, 2007, 07:12 Thanks for your replys. Be #4 New Member   Michael Krobath Join Date: Mar 2009 Location: Styria, Austria Posts: 2 Rep Power: 0 Thanks for your replys. Bernhard, you are right. My problem is "only" to calculate the temperature distribution within the solid (no fluid take part). But, I have different solid materials, with different thermal conductivities and they are (in worst scenarios) all temperature dependent. Michael
