[ GiDlist ] Continuation
Posted: Wed Jun 20, 2001 8:07 pm
Thanks very much for your help.
I still have a few questions, nevertheless.
" To create a new material, you can derive it from another previous material
(used of template for the fields), and then fill the value of the fields
modulus_(E)=2.1E6, etc. Then this new material can be assigned to geometry
or mesh entities "
Yes, but how can I assign a new material to a geometry ? which menu and
function do I need to use in GiD ? I have tried to, but I can't find
anywhere the description of materials. Do I need to import the material
characteristics in GiD from another program or file ?
" The initial stress, etc can be defined with a material or a condition
(creating an appropiate problem type). "
How do you create an appropriate problem type ? Which menu and
function do I have to use ?
" write a input file for the external analysis program "
How do I do so ? Sorry, but I am not very familiar with Linux ; I am
new to the plateform and don't know much yet about programming...
" To define a to stress-strain curve material, you can use grid field in the
material (variable number or rows). and define this curve by points in tho
columns. "
Again, using which menu and function ?
Thanks again for your support, and feel free to make any suggestions if they
can be helpful.

To create a surface polygonal of n sides, is entered the radius
of the circunscrite circunference.
For example, if yor enter a 4 sided polygon, centered at the origin, with
radius=10 then obtain:
You can also create a square, for example, creating the base line with
size=10 and then extrude
this line by translation to create the surface. (see Utilities-Copy).
When apply a zoom or pan, the figure not change of position, only change the
user view point.
Note: You can check the coordinates of a point with Utilities-Id.
The materials are loaded selecting firts a problem type.
To create a new material, you can derive it from another previous material
(used of template for the fields),
and then fill the value of the fields modulus_(E)=2.1E6, etc.
Then this new material can be assigned to geometry or mesh entities (best
assign only on geometry, meshing, the material are automatically assigned to
mesh entities).
The initial stress, etc can be defined with a material or a condition
(creating an appropiate problem type).
GiD unknown the significate of the fields of materials or conditions, only
apply this over the mesh, and write a
input file for the external analysis program (Tochnog).
It is also available generate structrured meshes of cuadrilateral and
hexahedral elements.
To define a to stress-strain curve material, you can use grid field in the
material (variable number or rows).
and define this curve by points in tho columns.
Write a file with a curve load-displacement is responsability of the
analysis program. (you can select with a GiD condition the node on this
result is demanded).
