Hi,
you’re right, Kenji Furui, the smoothed results of the first face
of the tetrahedra are repeated onto the other three ones. This
is a bug, and will be corrected in the next version.
The same happens to hexahedras.

It seems a bug of GiD postprocessing results on tetrahedrals with 4 gauss
points.
Use until a corrected version only 1 gauss point or extrapolate with your
code the results to the nodes
Thanks by your bug report.
Enrique Escolano.

Dear Enrique,
This is the simple example.
Please take a look at all faces of the tetrahedra.
One of the face shows the bug.
thanks,

Specify also as it is the GiD version used.

Dear GID members,
I think there is a problem when we visualize
results on gauss points(4pts) for quadratic
tetrahedral elements.
-----------------------------------------------------
Example:
in res file.
GaussPoints “Gauss” ElemType Tetrahedra
Number Of Gauss Points: 4
Natural Coordinates: Internal
End Gausspoints
RESULT “Pressure Profile” “SimpleCase” 1 Scalar
OnGaussPoints “Gauss”
Values
1 1.0
1.0
0.0
1.0
End Values
----------------------------------------------------
Then you’ll see the bug in one of the faces of the
tetrahedra.
Does anybody have the same problem?
thanks,
