irregular geometry
 

Dear friends, I would like to solve a problem of 3D transient conduction heat transfer. The system under consideration is a cylinder inside which a small cube of different material than the outer cylinder is present. Actually the geometry of the outer cube is very important to be simulated as close as possible to the reality, because its a source or heat generation. How can I simulate such kind of problem taking into account the real geometry of each components making this complexe system. Thank you very much for your contributions Cherif
