hello
I am trying to import a file dxf generated in autocad. It is a topographical map with curved of level each meter, but when I import to gid and they are drawned curve each five meters.
I need to know if the Gid has some restriction with the files dxf and what proceedings i must take to generate and import those dxf.
I work with autocad2000.
thanks
DXF Export:
GiD only export curves in dxf format, not surfaces or volumes (because the limitations of this format with Nurb entities)
DXF Import:
Before import, check your import preferences: Automatic collapse after import (to join duplicated entities)
and the import tolerance (automatic or manual, to select the tolerance to join entities)
Generally DXF is a bad CAD format, for solid models is best to export from AutoCAD in Acis format.
Send us your dxf file to check it.
Regards

You can create in the result file *.flavia.res a vectorial result: the
displacement
from the original location of each node, and select this result to draw the
deformated mesh at each time step.
Hi Enrique
can you post a small example of this?
Thanks

A lot of thanks Pablo
This is a small sample, with a 1 node element.
To see, change to postprocess and open the file .flavia.res or .flavia.msh
Open the Deform mesh window (menu Windows-Deform mesh)
and select Main mesh deformed, using result “Displacements”, with a factor=1
Then open the Animate window, select Deformation, and play it.

But i have a trouble because, i mesh my model, and then the solver generate new
elements for moving in every step.

If your mesh change between steps it is not available to use a displacement
result to visualize it.
You must write the mesh and result in separated files, one for time step..
It is also possible to create in GiD a specialized window programming with
tcl/tk, to animate your sequence of files.

Hi there
I attached the file of using time step (Nonlinear
Dynamic) with GiD..Take a look. Flavia.res file format
is very simple, I used the old format. If you want to
see more deformed shape just use Mesh Deform option
with factor=1, in PostProcess. I used 1/4 of Moley to
do analysis if you want to see nice shape just use
Mirror option.. Follow as Enrique adviced in
previous mail with the Animate.
Regards
