Problem with mesh in Gambit

1 Attachment(s)
Hi guy. I'm italian and For first i'm sorry for my english; i'm writing because i have a serious problem with gambit. in the picture that i enclose, there is a cylinder. I have mesh the surface 30, 31, 32 with elements: quad, type: map! when I mesh the volume, I select elements: HEX/WEDGE e type: cooper; for sources of cooper, i select surface: 30, 31, 32, but this is the result: ERROR: volume volume.11 cannot be meshed with only one connected set of source face. please help me. are the problem in the element that i indicated in the picture? is the geometry wrong? thank you very much for alla answer

select faces 30 and 32 as source.
I assume your volume.11 is a cylinder

problem 2

thank you very much mAx for your reply. Now i have another question! There is a comand for refresh drawing, because when the dimensions are very small, the circle for example became hexagon! thank you for your reply.

if the circle is hexagonal it is due to the number of nodes on your circle. I assume you only have 6 nodes. And 6 edges describing an circle is an hexagon

In the geometry mAx, no in the mesh

post a picture :D

refresh drawing

in this picture, you can see that the 4 circles intersect each other! this because the distance are very small: order of micron! if you could do a refresh, i can mesh the surface because in this moment this is impossible.

the picture!

I assume it is just a representation issue.
And you don't have meshing problems?

 giuseppemerlini March 3, 2010 06:13

yes, we have problem when we mesh surfaces, :(

upload your dbs file on a share server, I will take a look at it tomorrow

Cooper meshing face selection problem

Please I have a similar problem like the Main question, I have a cylinder volume and I like to use the HEX cooper technique to mesh the volume, noting that at the surface I split the surface the top and bottom using different shapes to control the mesh generated more and I split the side surface of the volume for the same reason of controlling the structure. the cylinder is upright as in the attached picture.
