[GiDlist] Shell element stress and strain plotting

[Jonas Forssell]

Hello, I'm using shell elements with several integration points through the thickness. In the current version of GID (7), I can only find that one stress or strain result through the thickness is allowed. Is there a way of showing more results in the element? A shell element under bending for example would show compression on one side and tension on the other side. Currently, I am using up to 5 integration points through the thickness in triangular and quadilateral shell elements. Thanks/Jonas Forssell, Gothenburg, Sweden

A GiD triangle or quadrilateral is an element without thickness (a thickness can be set using a condition or material pointing to the element)
Must use some trick to show a compression in a side and tension at the other side, for example write, for postprocess use only, a mesh *.flavia.msh with duplicated nodes and triangles. If exists a file named *.flavia.msh, then, changing to postprocess the preprocess mesh is avoided, and GiD postprocess use this alternative mesh.

Hello,

GiD does not impose any limitation to the number of layers of
integration points in
the planar element. You just must use a different result name for every
layer. For example,
you can have results names:

"Stresses layer 1"
"Stresses layer 2"
....

And you will be able to visualize all of them in the postprocess.

Additionally, you can also use TCL to change the postprocessing menus,
so as to find
a more natural way of presenting the results to the final user.

Regards,

Good idea!
Thanks for the help all of you.
