 February 6, 2005, 14:42 Heat Transfer & Boundary Conditions across 2D wall #1 SAAD Guest   Posts: n/a Hi; i am facing problems in 2D heat transfer. In 2D, how to model heat transfer across the wall. what would be the boundary conditions, if convection is taking place on both sides.I dont want to define any fixed temperature on the wall. Through convection, temperature should be defined automatically on the wall. if anyone can help me on this regards; Saad

I am facing problems in 'BOUNDARY CONDITIONS". any input would be appreciated

Fixed flux boundary condition, or alternatively a heat-transfer resistance/temperature combination. Check on your package... you could even go in & alter the user-defined boundary conditions... all depends on the package you are using. diaw...
