Convective heat flux

Please login with a confirmed email address before reporting spam

Hi,
I'm trying to see the heat conduction from the electric power conduit pipe to the soil surrounding the pipe.
The square part which I attached as model.png is the pipe and inside.
I built two point source inside.
Inside the pipe is just air, so I applied the heat transfer in fluid.
Wanted to apply convective heat flux to the pipe walls, but there was only inward heat flux in my version.
So I just applied the inward heat fluxes to the walls.
However, the result came out like result.png. Even though I applied heat transfer in solid and heat transfer fluid for the analysis, it doesn't read the heat conduction or convection inside the pipe box at all.
Anyone knows the solution? using inward heat flux to realize the convective heat flux or finding the convective heat flux.

Is it just the problem of this version?
