Smoothed results in Gauss points

Hello,

I have a problem representing results in Gauss with different numbers of GPs that GiD has as natural.
Im trying to represent the result in tetrahedral elements with 14 gauss points and triangle elements with 7 GP with this configuration:

GaussPoints "Triangle7" ElemType Triangle
Number Of Gauss Points: 7
Natural Coordinates: Given
0.33333 0.33333
0.16667 0.16667
0.66667 0.16667
0.16667 0.66667
0.41667 0.41667
0.16667 0.41667
0.41667 0.16667
End gausspoints

GaussPoints "Tetrahedra14" ElemType Tetrahedra
Number Of Gauss Points: 14
Natural Coordinates: Given
0.33333 0.33333 0.33333
0.16667 0.16667 0.33333
0.66667 0.16667 0.33333
0.16667 0.66667 0.33333
0.41667 0.41667 0.33333
0.16667 0.41667 0.33333
0.41667 0.16667 0.33333
0.66667 0.66667 0.66667
0.16667 0.16667 0.66667
0.66667 0.16667 0.66667
0.16667 0.66667 0.66667
0.41667 0.41667 0.66667
0.16667 0.41667 0.66667
0.41667 0.16667 0.66667
End gausspoints

But i only get the representation of the results like a coloroured point on the gauss points not a smooth result over the surface.

I have been reading in the forum and i found some old topics speaking about the same and with answers that GiD doesnt makes the representation if the points are not the numbers of points that GiD has as natural.

I want to know if there is already some solution to make this representation or should we extrapolate the results to the nodes or to a number of Gauss points natural for GiD.

Thank you.

Greetings.

For results visualization I recommend you to interpolate your 'non-standard-GiD-gauss points' to a standard quadratic or linear element (20 or 4 nodes tetrahedron) and (6 or 3 nodes triangle),
or write your results as an averaged smoothed nodal result, then the result will be continuous between neighbor elements and you could use some extra GiD tools like calculate streamlines on a vector field.
