Hi,
How can I create both tri & quad elements on a single face as shown on the attached file ? Quad and tri elements are not separeted with a line. Thank you in advance. |

with a BL you can obtain someting like your pdf.
But you won't have quads pressing of opposite edges (left bottom corner on pdf). Else without a split, I don't know how (and I wonder if it is possible)

I tried to attach a BL, as shown in attached file, it didn't work. The Bl doesn't touch the vertices on the left side of the bottom.

Do you think I can do such a meshing with another tool? Any idea?

with gambit, you only need to split the surface and that's it!

Splitting like that creates a line which needs to be defined as an interface. This is not desired.

no
If your split is well done, your line will split the surface into 2 connected surfaces. So interfaces aren't involved here

Please just have a look at the attached file.
It is created with a design modeler. It has a box and a triangler face. There is no line between the faces. It has no vertex on the line shown with a red arrow. What a pity. I can't do it with a Gambit. Any |

I don't understand where is the problem, with the separated line.
Once again, if the 2 surfaces are connected, the line will be treated as element's edge. If you import your mesh if Fluent, you can display the mesh, and you won't see the line anymore:just like what you want. But I give your right, if the 2 surfaces aren't connected, then, the line will be treated as wall, and then you need interface Sans titre.png

by splitting your surfaces into 2 surfaces. Then mesh first surface with quad and the other with tri
