[GiDlist] results on gauss points for tetrahedras .

Post by kenji furui »

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,

Post by V.SAYAKOUMMANE »

Hi Kenji
As my experience, to get the smooth contour of the
results,in GiD, you have to have the result values on
the nodal points, not in Gauss points. YOu can have or
plot results on Gauss points but your Post-processing
result will not be smooth as expected. YOu know that
the results of FEM never smooth by element to element.
I don't know if GiD.7 can plot the results on Gauss
point as a colored ball.

regards.

Please, send us the complete files .flavia.res and .flavia.msh
(or all the GiD model files if not exist this .flavia.msh)

Specify also as it is the GiD version used.

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,

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.
