Gambit copy/reflect operation
 
Hello,

I'm using the option copy/reflect of Gambit on a group of meshed edges, in order to make a whole domain from an half domain. In the half domain, each jonction between faces is composed of a single edge, but in its symmetric part obtained by the copy/reflect option, there is two edges. So, when I use Fluent with this whole domain, it does as if there were walls between the new faces ! How can I do to generate a new half domain with only one edge between new faces ?

Thank you for your help

Use the 'Connect edges' feature, and select all edges. That will delete any extra edges and vertices inside your model.

Hello,

Here, some informations to be sure to create a good geometry :

In fact, when I've tried to create a whole geometry from an half geometry, by creating a group containing only edges, and by symmetrising them, Gambit didn't accept to save the whole geometry and said :

Received exception: Assertion failed in GdbObject.cc, line 987: 0

I think it's because there are relations between each entities of the geometry (vertice, edge, face) that weren't respected by creating a group containing only edges.

So I've made the same operations but by creating a group containing all the entities, and no error was signaled by Gambit.

Have a good day !
