Hi all,
I have a sphere fluid flow in a channel.
I want to study conduction in the sphere
1) I create 2 zone ( 1 fluid zone and 2 for solid zone (sphere)).
2) I set all interfaces between solid and fluid to wall.
3) After exporting mesh to fluent, I see a -shadow boundary condition of type wall for each interface wall.
4) I enable heat equation. (knowing that the two wall are coupled)
5) Fluid flowing at 0.0001m/s water,370K
6) Sphere (copper) 300K initial temp.2spheres attached together....

Grid convergence has to be done...so Steady state simulation was tried...though the solution converges....
the problem after running simulation there no transfers conjugate between fluid and solid the temperature of solid remains stable (initial temperature).

Please help me ..give me suggestions regarding the Setup of case esp boundary conditions...

Thanks in advance......
