Hello,

I have 120 volumes with a total of 600 faces. I am trying to copy these volumes by translating them 2o units in the positive z direction i.e. significantly away from itself so when it copies it does not duplicate and faces on the same boundary.

However when I have copied instead of showing 1200 total faces I am getting 1320 faces somehow. The number of voulmes doubles as it is supposed to to 240.

Why is the number of faces increasing by 120 i.e. by the number of original volumes being copied?

The copied volume and the original are not touching.

Thanks anyone

Just a guess - the new ones are not conected to each other. If you copy volumes, they are copyed one by one you have to connect them with the face connect option. hope thats it

Hi,

I get what you are saying about the connected geometry thing but this only seems available when you Move rather than when you Copy.

I am trying to copy.

Any suggestions please? Thanks

No I don´t mean the connected button when moving. I mean :

First copy the volumes THEN you conect the faces

choose faces-button and then conect-button ( right to the unit-faces ) Take all faces of the new volumes Apply

Gernot,

Thanks very much mate, I ahve tried what you suggested and it works perfectly.

Again thanks for your help, I love this forum.

This is true. Copying connected geometry causes it to become disconnected which can be a useful way to diagnose problems. You can see this if you colour entities by connectivity rather than topology and compare the original and copied geometries.

After copying the volume, the faces are disconnected and has to be connected again to define volume but some of the faces will be duplicated during the process of copying.

Then what would happen to those faces that are copied twice?? Do we need to find them out and delete them or they can remain there? if they can remain there, then what would happen to mesh generation??

Thanks in advance

You can connect or delete them, it depends on your geometry.
I think non-meshed faces will not be exported to the msh file; but better to have a consistent geometry..

I have couple of volumes which are linked to each other by some faces (interior faces). Now, I wish to copy these volumes couple of times. After copying, I can see each volumes (I mean Gambit does not disconnect their faces). However, the problem is that faces which are common between the volumes are copied twice (separately for every volume) and I can not delete any of the extra one because it belongs to upper topology (volume). So, I suppose this effects the mesh generation and also in defining the boundary conditions.

Any help or suggestion?? tanx


Hopefully I explained it in a good manner!!

Delete the volume, not the lower topology, delete extra faces, then recreate the volumes.

meanwhile, I am copying the faces instead of the volumes and then stitch faces to define volumes. This way I will avoid the creation of some interfaces which are sharing the same surface in two volumes.

But still waiting for some solution to my problem

Thank you very much
