Geothermal ground coil
 

Hello every body, first of all sorry for my English langage (it's not beautiful)
So, I'm studing on a geothermal system which is a geothermal vertical coil, it's a new experiments in France and I'm in charge to simulate tid system.

Anyway, for my part, I've already model the system, including pipe, coil, and ground but,
the thing is, I can't fullfil domain with right features.
It's tough software and I'm just on the second part of the workbench.

I mean now I'm on CFD but I would like to know if it's better on fluent.

If someone has already done this system, can you help me please.

Regards
Ben
