Hello Guys
I am new to this forum. I started using ansys 2 months ago and till now I don't know how to choose the interior of a body. Attached is a picture that explains my problem. I have drawn a small sphere and frozen it. Then I drew a big box around it and subtracted them from each other without preserving the sphere. Now I want in fluent to define the interior surface or the sphere as a heat source. How can I do this??
Thanks in advance

on top, you can filter the selction to points, edges, surfaces, and bodies. you have to toggle on the surface selection. then select the surface of the select. right button click -> rename selection, give it a name first: like WALL_SPHERE. once this will be meshed, it will appear in fluent as a boundary condition

Thanks Diamondx but I didn't manage to solve the problem. I tried what you have said but I couldn't locate the interior sphere surface?? What can I do?

hello mr mohammed,
go to the mesh ,before you make a mesh , make a right click on any face and then select hide face ,then you can select the ball and make a named selection for it this way you can select and define any part on your geometry
best regards

Thanks a lot Guys Haydar and Diamondx. I have located the sphere by doing what diamondx has initially implied and used the planes that appear down-left to choose the hidden face.
Thanks again
