Hi,
I am supposed to model heat transfer between spheres (solid) and fluid (the space) and I have a few questions related to the simulation. I will really appreciate if someone who did the same simulation before helps me on this issue. My problem is related to interface and boundary condition and I couldn't run.



Many thanks

Most of us here could help you. I doubt it's common to have run the same simulation as you. I haven't, and wouldn't, as I would have used symmetry, (up to 1/8th) with perhaps periodic translation in the Y direction. So my model may have been about 32x smaller.

I said "same" not "exactly". I know that most members want to help but you know sometimes a wrong advice causes wasting time. my account is new but I am not a new member. Once this site was very helpful to me and so many things about fluent I have learned from this site, since when I asked a question, those members who had the same experience answered and shared their precious ideas.

By the way, I solved my problem.

Kind Regards
Hamda

Dear Hamda,

Thank you

If possible, please explain what your problem was and what was the solution you found.

As you mentioned, the experience you gained might be helpful to someone else searching the forum in the future.

Cheers
