[GiDlist] Two assembled faces but with different number of

Postby Isabel Gil » Mon Dec 11, 2006 3:06 pm

Hello Gid's users,

Some days ago, I made the following question:

"*I have a question about how I must work when I have two different
layers but which are assembled.
I must say that is a simple case in order to know the proper way to work.

I create the first layer (a 3D cube) and I create its volume, as it is
said in Gid manual. Later, I create the second layer which is another 3D
cube and, again, I create its volume.

When I show these two layers and I mesh it, the face shared by the two
cubes contains the double of nodes (ones for the first layer and others
for the second one). What I really want to get is to have only a series
of nodes in that face*."

Julian advised me to use (Utilities-collapse) and I got my aim. But
now, I would like to obtain another different goal. I would be very
grateful if you could help me.

I want the face of the first volume (which is on the first layer) to
have the double number of nodes than the face of the second volume
(which is on the second layer) but that the name of nodes that both
faces share, fit in.
Perhaps if I show some pictures, I can make easier what I want to say:

Name of nodes on the face of the first volume (one layer):

1_____2____3___4____ 5
| | | | |
|6_____|7___|8___|9____|10
| | | | |
|11___ |12__ |13__|14___|15


Name of nodes on the face of the second volume (another layer):

1__________3_________ 5
| | |
|6__________|8________ |10
| | |
|11_________|13_______ |15

It is clear that now I cannot use (Utilities-collapse). Any advice will
be welcome.

Thanks in advance and best regards
Isa

You need to create different surfaces for each volume, not a shared one, because it seems
that you want non-conformal neighbor volume elements.

In other hand, you can share, if you want, some points/lines of neighbor surfaces.
If you share a geometric point/line, then its nodes will be shared between generated mesh elements.

Hello!
Thanks for your quick answer.
Then, you mean I don't have to use (utilities-collapse-volume) or
(utilities-collapse-surface) but I should use
(utilities-collapse-points) and (utilities-collapse-lines), shouldn't I?

But if I do it in that way, I won't share the same dofs because they
will be different ones and I would like them to have the same names
because they are the same ones, not different ones with the same names.
Sorry for asking such a cumbersome question but thanks in advance and
best regards!

Hello,

I'm not sure if I understand your problem, but may be I can help you.

If you want that the volume meshes share some node, that node must come from
the same geometrical point. In your case, If you want some internal node of
the "contact" surfaces not to be duplicated, you must divide the surface in
the way that in the position of that node must be a geometrical point (which
must belong to a line of the surface).

Regards,

ABEL
