Boundary types in Gambit
 
can anybody tell me what is the difference between the boundary types: INTERIOR and INTERNAL in GAMBIT (BOUNDARY SPECIFICATION MENU) and when can one define a face (in a 3D-geometry) as INTERNAL or INTERIOR

Thanks in Advance

Practically, interior doesn't mean anything. A surface is there without any function. (interior like the whole volume is). You cannot adjust anything.
Internal can have some specific properties (thickness e.g.)

I am working in a heat transfer over a fins with an inlet velocity of 1m/s and heat flux of 100W amd everytime I run it in fluent I get this
Error:
FLUENT received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.
Error Object: ()


Does anybody know how I can fix my error and where can I get a explanation of my error
Thank you

hi,

even im working on the flow over fins. I got that error and was able to rectify it.. what are your boundary conditions? in my case i have modeled a tube (water flowing through)a nd air flowing across.. the tube runs through a fin like a heat exchanger. i am having trouble giving the boundary conditions for the tube walls. any suggestions?

Interior simply means they are fluid edges, not walls or anything else.:eek:

I got the information from the following URL:

Have fun:D.
