Analysis of a solid

The example used to describe the solid analysis will be a cantilever beam with diminishing cross section.

For basic reference, this example can be found in the distribution, directory Examples/RamSeries and with the name manual-solid-ex4.gid

The first step is to create the geometry. It can be defined using the GiD preprocessing commands described in the GiD manual. The final model will be composed of 1 volume, 6 surfaces, 12 lines and all of its connecting points. Some useful commands are:

Geometry->Create->Line

Geometry->Create->NURBS surface->By contour

Geometry->Create->Volume-> By contour

Be careful to position the structure related to the global axes as seen in the picture. Then, it will be easier to follow the example. The eight points will be:

A

0.000000 0.000000 0.000000

B

5.000000 0.000000 0.000000

C

5.000000 0.500000 0.000000

D

0.000000 0.500000 0.000000

E

0.000000 0.000000 –1.000000

F

5.000000 0.000000 –0.500000

G

5.000000 0.500000 –0.500000

H

0.000000 0.500000 -1.000000

After creating the geometry the GiD window will be similar to this one:
