Two solids 2D CHT Analisys

I'm trying to do a 2D analisys(one element thick mesh) to investigate the cooling efficience of a copper bar covered by an insulation layer. A source subdomain is assigned to copper region taking into account the effect of current flow.
I obtained a good temperature distribution for the colling fluid, but the copper bar calculated temperature is 0°K. I think I set right parameters for solid-solid (copper - insulant) interface. I dont understand what happens... Can someone help me? Thank you. |

Hi,
Obviously something is wrong with your physics setup. Check all parameters affecting heat transfer. It could be anything from material properties to interface conditions to boundary condition setup. Glenn Horrocks |

... i think you are right. But I dont understand where error could be.
I used a source subdomain in copper region, solid-solid interface between copper and insulating layer, solid-fluid between insulant and air. I choose the automatic mesh connection method. The one elemet thick mesh is obtained extruding a 2D mesh in ICEM CFD. Materials come from CFX library (Air ideal gas). I also tried to analyze a much simpler model having similar features, and results were wrong again. Have you got some idea? If you want I can send you my files. Thank you. |

Hi,
I don't have time to debug people's simulations. If you need detailed help talk to CFX support. Build your model up one component at a time and check each part is working correctly as you assemble it. This takes quite a bit of time but is the only way to be sure. Glenn Horrocks |
