Dear GiD list members,

I am trying to model a 3D frame, which has beam elements, with 3 nodes and
truss elements, with 2 nodes. If I use the option "Meshing/Quadratic
elements/Quadratic", only linear elements with 3 nodes will be generated
for the whole model. On other hand, using the option "Meshing/Quadratic
elements/Normal", only linear elements with 2 nodes will be generated for
the whole model.

Is there a procedure to create 2 and 3 nodes in a single model? I am using
the 6.1.2 version of GiD.

Thanks in advance

In GiD, all the mesh is considered as quadratic or linear.
In order to have together both types it is necessary to make some "trick".

For example, a condition named "Truss" can be assigned to some lines, to
mesh all quadratic , but in the elements with this condition only two nodes
for the calculation are written, ignoring the central node.

Another possibility would be:
1- Mesh the linear elements
2- Write the mesh in disc (Files-Import/Export-WriteMesh)
3- Mesh the quadratic elements
4- Reload the linear mesh (Files-Import/Export-MeshRead) option
AddNoShare
5- Collapse the mesh to join superposed nodes.

Regards

Hi,

It seems as if the "Multiple windows" option is
not working in the recent beta version..?! GiD
crashes with "Segmentation fault" whatever window
configuration is chosen.

I am running it on an SGI O2 workstation under IRIX 6.5

Thanks to inform to us into the problem.
We already know this bug, in the next version will be corrected.
