Dear Sebnem

There are several ways of defining sets in GiD. They basically depend on the
way you work with it. As you know, GiD allows working like an end-user and
working on the development of interfaces with calculation codes.

a) DEVELOPING INTERFACES

On one hand, if you work developing interfaces, you can include in your
materials file and/or conditions file some generic sets (see example in part
c).

b) AS AN END-USER

On the other hand, if you work as an end-user you can select sets of nodes
or elements. Afterwards, you can assign the material and/or condition you
are interested in to the this selection.
Visualising the mesh, you will be able to select specific groups of
nodes/elements and assign different labels. If you want to define sets by
geometry, you can add other conditions in agreement with the geometric
entity you want to use.

c) EXAMPLE:

FILE OF MATERIALS

problemtype.mat file:
NUMBER: 1 MATERIAL: Set1
QUESTION: Name
VALUE: Set1
END MATERIAL
NUMBER: 2 MATERIAL: Set2
QUESTION: Name
VALUE: Set2
END MATERIAL


FILE OF CONDITIONS

problemtype.cnd file:
NUMBER: 1 CONDITION: SetNodes
CONDTYPE: over surfaces
CONDMESHTYPE: over nodes
QUESTION: Name
VALUE: Set1-Nodes
END CONDITION
NUMBER: 2 CONDITION: SetElements
CONDTYPE: over surfaces
CONDMESHTYPE: over elements
QUESTION: Name
VALUE: Set1-Elements
END CONDITION

I cannot figure out how to define "sets" in GID,
i.e. choose a certain number of elements or nodes
and name them as a set.
Any suggestions?
Thanks.
