Hello,
The easiest way to create a contact between two nodes is the
following:
- Create a condition 'master', to be assigned to nodes, with a
field that identifies it.
- Create a condition 'slaves', to be assigned to nodes, with a
field that identifies it.
Assign both conditions, selecting in both the same identifier.
The identifier can be either one entry field, where the user writes a
name or can be
a menu with several predefined identifiers.
In the GiD version 7, there will be new possibilities to change the
appearance of the input
widgets so as to make it easier for the user. For example, it will be
easy, with the help of
TCL-TK, to input the identifier as a combobox where it is both
possible to enter a new name
or to select an existing one.

Asunto: Re: [ GiDlist ] Contact Surface
The "line-contact" (to create a union degenerated between two points) is
not implemented in GiD, it is only implemented the "surface-contact ", and
the "volume-contact".
At this moment it is necessary to use another alternative, like for
example:
- Create a line (of null length) between points, and assign some condition
to him to distinguish it
(Note: if "collapse" is used it destroys this line).
- Or create a condition with thwo fields: the number of the two nodes (The
user must write the numbers manually, and if renumber or remesh this
information remain obsolete).
In the future will be added the option "Line-Contact " directly inside
GiD.

Hello, all
I want to create the zero-length element for spring between two beam
element.
For example, I have two beams, first one has coordinate as (0,0) and
(10,0), and second one has those as (10,0) and (20,0). Now I want to have a
zero-length element at coordinate (10,0) for spring. Do I have any way to
create this model in GID?
thank you

thanks for the possible solution of my problem.
Basically I got two possible answers to create a kind of contact line.
But, I'm not sure yet about all three recommendations. Followings are
each answers from you and my additional question.
1. Create the null line using the two nodes which have the same geometric
location and allocate the condition to identify the null line. In this
case, how do I create the null line? And can I allocate the material on
the null line?
2. Create the master and slave nodes using condition. In this case, how do
I select the master and slave node from gid window since there are in same
geometric location? Do I need to use layer concept for this? Or can I
define those in *.cnd file? And Can I allocate the material to this even
though I don't have the physical element inside Gid. Could you please give
me more detailed information for this case?
I appreciate your help
