GaussPoint -

Postby davidg2 » Fri Aug 11, 2017 4:54 am

hi,
I would like more information about the formating of the values for the Gausspoint in the post-processing file

My problem is that, in the post-processor the result I present 6 cases of stress, but SXX and SXY is wrong but the other values are ok.. All values are fine in the archive ".res"
I'm using GID 13.0.2 for Mac
MacOs Sierra v 10.12.6

GaussPoints "H8" ElemType Hexahedra
Number of Gauss Points: 8
Natural Coordinates: Given
-0.577350269 -0.577350269 -0.577350269
-0.577350269 -0.577350269 0.577350269
-0.577350269 0.577350269 -0.577350269
-0.577350269 0.577350269 0.577350269
0.577350269 -0.577350269 -0.577350269
0.577350269 -0.577350269 0.577350269
0.577350269 0.577350269 -0.577350269
0.577350269 0.577350269 0.577350269

Hi,
I am not expert in gauss points, I just extract the information from

https://www.gidhome.com/documents/customizationmanual/POSTPROCESS%20DATA%20FILES/Results%20format:%20ModelName.post.res/Gauss%20Points

On hexahedras internal coordinates:
a=0.577350269189626
(-a,-a,-a) ( a,-a,-a) ( a, a,-a) (-a, a,-a) (-a,-a, a) ( a,-a, a) ( a, a, a) (-a, a, a)

So it seams that the order of gauss points is not the correct.

Return to “Postprocess”
