Subject: [ GiDlist ] contact elements with tetra10
Hello,
is it possible to create contact between tetra 10 nodes elements?
The GiD manual about contact volumes says that only Prisma elements with 6
nodes (contact between tetra 4 nodes) are possible.
In GiD6.1.5b every test ends in error.
Thank you in advance and regards.

[ GiDlist ] contact elements
For GiD, a contact is only a node-to-node link. It is interpreted as a mesh
specification to create two identical meshes, and connect the nodes with
prism element (named contact elements).
Another type of contact is unkown for GiD. Usually a problem type define
conditions, for example, named "Source" and "Target" and is applied in GiD
to two families of surfaces (transferred automatically to elements or nodes
of the mesh). The condition stores the contact properties (friction, etc.)
and a ID common to Source and Target (for more than 1 contact).
I' not know if this form to treat a contact by means of a condition adapts
to your case. It would need to know that it exactly expects of the file
input the analysis program.

Hello;
Imagine, i want to study a contact between two bodies, so one body slide
over
another body, like when i push a book over table. This kind of contact, i
known
like node-surface, source contact and target contact. It is possible to
create
in GID?
thanks again

For GiD, a contact is only a node-to-node link. It is interpreted
as a mesh
specification to create two identical meshes, and connect the
nodes with
prism element (named contact elements).
Another type of contact is unkown for GiD. Usually a problem type
define
conditions, for example, named "Source" and "Target" and is
applied in GiD
to two families of surfaces (transferred automatically to elements
or nodes
of the mesh). The condition stores the contact properties
(friction, etc.)
and a ID common to Source and Target (for more than 1 contact).
I' not know if this form to treat a contact by means of a
condition adapts
to your case. It would need to know that it exactly expects of the
file
input the analysis program.

Subject: [ GiDlist ] contact elements
Hello;
Imagine, i want to study a contact between two bodies, so one
body slide
over
another body, like when i push a book over table. This kind of
contact, i
known
like node-surface, source contact and target contact. It is
possible to
create
in GID?
thanks again

Actually only is available the element contact prisma of 6
nodes (from
linear triangles 3 nodes) or the prisma of 8 nodes (from
linear
quadrilaterals of 4 nodes).
We will study the possibility of including the quadratic case
next.

Subject: [ GiDlist ] contact elements with tetra10
Hello,
is it possible to create contact between tetra 10 nodes
elements?
The GiD manual about contact volumes says that only Prisma
elements
with 6
nodes (contact between tetra 4 nodes) are possible.
In GiD6.1.5b every test ends in error.
Thank you in advance and regards.
