[GiDlist] Post Processing on given gauss points for tri3 and

[Guy HUBERT]

I am currently developping the interface between Gid 7.2 on Windows and a
finite
elment solver.

1 - I have a shell mesh with results defines on gauss points on triangle
(T3) and
quadrilateral (Q4) elements. When I want to show contour, I have to choose
T3 or
Q4, but I cannot view T3 and Q4 on the same image, I try to use "Several
Results"
but I cannot add more than one result.

2 - For results defined on Quauss Point (Given), how Gid decides to display
result with contour or with colored points located at gauss point location ?

Thanks

Hi,

1. there is no way to show a c.fill of a result defined on two different
gauss points sets at once.
2. by given natural coordinates, gid tries to extrapolate the results
to the nodes of the element:
1/3/6 gauss points per triangle
1/4/9 gauss points per cuadrilateral
1/4 per tetrahedra
1/8/27 per hexahedra
(download the 7.4.2b version which solves some interpolation problems),
and if this is not possible, then it will draw the gauss points result
as coloured spheres. Nevertheless you can always label the gauss point
results which will be located at the gauss points.

a question for the list:
does anybody know which are the natural coordinates for 10 Gauss points
in a tetrahedra?

Hello,

I haven't found anything on this level of integration, several
publications give 1, 4, 5 or 15 gauss points on tetrahera.

I join the Code_Aster documentation with weight and coordinates
of integration points. The same are reported in
"Finite Element method displayed" from Touzot and Dhatt.
