solving multiphysics problems

sir,



i am trying to solve a multiphysics problem which includes heat transfer and fluid flow . but when i solve all my equations together ,the solution is not converging. so i tried to solve sequentially. but i do not know how to link each solution to other module.for example after solving for heat transfer i cannot use that solution to compute velocities in laminar flow module.



please help......,

Hi

have you checked the "Conjugate Heat Flow" section of them physics and the related doc ? be aware that coupling these two physics is tricky, and require careful tweaking (= reasonable knowledge of expected results to define "good" initial values)

Good luck
