Hello, this is sort of a follow-up to a previous post.
I made a 10x10x10 box with 1-inch thick walls. There is one inlet and one outlet opposite each other.
I am trying to do a simple fluid flow in FLUENT through the inlet to the outlet. My wall temperature at 320K and the air inside initially at 300K.
No external boundary conditions. Wall-Fluid Boundary Coupled. Standard initialization at 300K, Box patched at 320K.
Inlet set to 0.5 m/s velocity magnitude.
Using k-epsilon viscous model.
Everything appears fine in my set-up, but when I run the calculation my energy residual goes through the roof, setting insane temperature readings. Any idea what is causing the non-convergence?
