[ GiDlist ] troubles with meshview

[Blas Molero - Tecnologías CAE Avanzadas]

Dear Pablo,

In general in GEOSTAR you can plot "faster" shaded Shell elements mesh without geometry associated, but the hidden line algorithm is not always successful in plotting the elements correctly, especially for 3D solid models (Bricks & Tetras), so different techniques can be used to correct the displays.

Yesterday I explained "to remove geometry association" of the elements during the plotting process, but also the z-buffer algorithm (Display Display_Option Set Hide Option) will usually do the trick of correcting the hidden line plot. The z-buffer algorithm is more robust but is much more CPU intensive and can take relatively long times for display especially for large models.

The z-buffer algorithm along with the removal of geometry will always solve any plotting problems for 3D solid elements !!

Cheers!,
Blas.

Thanks Blas, i will try, with shell elements export without geometry i never have troubles.

Regards,
Pablo

Dear Pablo,

In COSMOS/M Geostar you don´t see anything when plotting elements because the mesh is not associated to geometry, the information you can import from GiD is only nodes & elements, not the geometry (Curves, Surfaces, etc..).

You can display mesh simply issuing the following commands:

. "BOUNDARY,1,0" command from "Display, Display_Option, Set Bound Plot" to plot boundary element faces only not associated with a surface or region
. "EVAL_BOUND,1,0,20,1" command from "Display Display_Option Eval Element Bound" to evaluate boundary faces,
. "SHADE;" command to activate shading of element plots, and finaly
. "EPLOT;" command to plot ALL elements.

You have this problem well explained in our COSMOS/M Support page in the following address:

Best regards,
Blas.

Hi to everybody
When i generate tetrahedra elements, then meshview does not work, so i can see
the mesh in normal mode, but when i do render filled nothing to see, and when i
export to cosmos it happens the same, i can see the mesh with no hidden, when i
try to render, nothing to see.
Anybody can help me .
advanced thanks
