interior and internal boundary?
 
Could anyone tell me the difference between interior and internal boundary ,in GAMBIT? THANKS!

Re: interior and internal boundary?
 
interior is the fluid area, the area in which your fluid"moves". internal boundary can be something like that:inlet,outlet,wall..namely a boudary of your fluid. Did i help?fell free to ask Regards

hi john inernal and interior in gambit is same when it comes to fluent. both will be visible as interior only. if go to tgrid then makes a lot of difference when you export surface mesh to tgrid and trying to do mesh there then surfaces which defined as interior will be unavailable and only internal surfaces will be available for giving boundary conditions this is my opinion. if it is wrong please correct me. thank you

Hi,john how about differences between interior and interface,interface and internal boundary ?

for example ,volume A splited with volume B(selected "connected"),now ,the face(only one face) between the two wolumes ,is interior ? or interface?

thank you ! macelli

it is certainly comes under internal in tgrid where as interior in fluent.

Hi,

Is the similarity between interface and interior boundary condition applicable to a 2D geometry where an edge connecting two different faces (with different meshes) is assigned the same?

Thanks in advance.
