[GiDlist] Viewing results on Gauss Points

Post by Louis Christophe »

Hello,

I am currently studying problems for which I would like to view different fields on Gauss Points, and I have a question about the post-processing of such problems. In some cases, I have triangles and quadrilaterals together. So I have to define two kinds of Gauss points (for triangles and quadrilaterals), but the problem is that, in the post-processing, I don't know how to view simultaneously the results on these two kinds of elements.

[GiDlist] Viewing results on Gauss Points

At this moment, it's not possible to simultaneously show this triangle and quadrilateral results.

A trick to solve this is to write an auxiliary mesh "*.flavia.msh", for postprocess pourposes only,
splitting each quadrilateral in two triangles.

[GiDlist] gid and boundary conditions

Post by Anke Griesbaum »

Dear Gidlist-members!

I'd be appreciate if You had the time for one question!
Is it possible to assign boundary conditions in GID7.2 Academical
Version?
The 'conditions window' in the data menu is not existent!

[GiDlist] Cant see any contour lines

Post by Ambrose Thompson »

Hello,

I wonder if someone can shed some light on this.

At the postprocess stage I import several meshes and results.

My result file follows this pattern

.....
GaussPoints "pexterior" Elemtype Linear "POLAR"
Number of Gauss Points: 1
Natural Coordinates: internal
End GaussPoints

GaussPoints "nexterior" Elemtype Quadrilateral "NORMAL"
Number of Gauss Points: 1
Natural Coordinates: internal
End GaussPoints

.... etc etc

then a series of results of the form

Result "P Phase Pol" "Analysis Name" 1 Scalar OnGaussPoints "pexterior"
Values
...
...
End Values

Result "P Phase Nor" "Analysis Name" 1 Scalar OnGaussPoints "nexterior"
Values
...
...
End Values

The MSH file is of the form

MESH NORMAL DIMENSION 3 ELEMTYPE QUADRILATERAL NNODE 4
COORDINATES
...
END COORDINATES
ELEMENTS
...
END ELEMENTS

MESH POLAR DIMENSION 3 ELEMTYPE LINEAR NNODE 2
COORDINATES
...
END COORDINATES
ELEMENTS

The problems I am having is displaying contour lines and viewing multiple results and using border graphs. When I select contour lines I only see the borders and a small coloured cross - however, contour fill worked just fine. I would like to display all the results and I cant seem to get 'Several' results to work (I select 'one over another' and each time I change the result it defualts back to 'one by one' and disposes of the previous result id). In addition when trying to select a border for border graph I am unable to do so.

What am I doing wrong

Thanks
Ambrose
