How to name inner domain in Gambit
hello..
I have a large domain D.. I have one shape,S ( exotic shape) in my large domain.. I had drawn another small domain,X to surround my exotic shape so that i can mesh finest mesh around this and coarser elsewhere.. In gambit i had done X subtract S, then i retain both faces.. Next I did, D subtract X... I had meshed my small Domain X finely and the bigger coarse.. everything was fine.. problem is my boundary condition.. what do I name the inner domain? please help.. |
don't give any name of internal domain.

hello
If i do not name it.. In openFoam, it is taken as default Wall.. Please advice. |
You were talking about inner domain. So I understand a volume.
Then I assume you have wall between your default domain D and you refined domain X. This is typical connectivity problem. So you have to connect those surfaces A picture is always welcomed |
hi its in 2D..
|
inner shapes are wall..
|
If you are working in 2d then bc are set on edges. (so you have to connect your edges)
I don't see anything on your picture |
when i do connec the edges i obtain the attached error..
I want wall only the buildings.. i have subtract the small square( domain) from the big domain.. and subtract the buildings from the small square domain.. |
upload your dbs file in a share server, I'll check

Ok as I thought: you didn't have any split.
So: - go to face substract, and select face.2 as "face", then select all faces (except face .2 and face.1) in "substract faces" -Now you have only 2 faces: face.2 (the one you generated with substract) and face.1, which you will use for the split -go to face split, and selet face.2 in "face", and face.1 in "faces" Now your domain is ready, you can mesh Attachment 26361 |
hi
you mean now on doing this, i can name my edges and not bother with the inner square? also in Quote:
|
you just have to select the faces:
the first ("face") is the surface from which you want to generate a split. The other ("faces") is the surface (or surfaces) you want to use for splitting https://www.sharcnet.ca/Software/Gam...plit_faces.gif |
So for me
face2 is the first and face1 is the second.. Thankssss |

Hi max
Hwo do i close my volume? when i do stitch volume, i got the error of Quote:
|
you have to create each volume and then again the substract and split stuff (but with volume)
|
hi max
thanks for a reply.. When i create volumes.. Ie stitch all my face together.. i obtain the Acis error..:( |
give me an example
