[GiDlist] Some problems with Gauss point results

[Andrea Calaon]

Hello everyone,
I have some problems trying to display gauss point based scalar
results.
I just tried to represent a non linear scalar field on only one
triangular element with 6 gauss points, here is the example.
Can you see the problem?
Do you have any suggestion?
Thanks in advance

The problem is that gid extrapolates de gauss point values to the nodes
and the draws the triangle.
As the triangle has only three nodes, it draws a triangle
with a constant value, i.e. only one color.

You can select 'Display Style-points' and you'll get coloured
spheres located at the gauss points with their values.

You can also enter 6-noded triangles to see the variation inside
the triangle, but i've done already and found that, with the current
version, it does the same as with the 3-noded ones.
i've fix it and will be available for the next version.
