Gauss point visualization error with Paravis
Gauss point visualization error with ParavisPosted by Lorentz at September 29. 2012
I consider a single HEXA20 element with 27 Gauss points, see attached file. But when I try to plot the Gauss points with PARAVIS through one of the the filters GenerateQuadraturePoints or GaussPoints, the Gauss point positions are obviously wrong (as can be confirmed through a comparison with module VISU).
Is this a misuse of PARAVIS or of the MED format (interlace mode ?) ? Did someone encounter the same issue ?
Thanks in advance.
This bug has been reported some weeks ago in the Code_Aster forum here:
It is reported by TdS to have been entered in the bug tracker.

Thanks Pierre !
Curiously, as far as I can remember, it works well in 2D...
I believe that gauss point visualization has been validated on "solid" structures (meaning not thin structures)
Thus, while I have not checked, I believe the bug does appear when considering a single layer of hexa20 / hexa27.
I have not checked how the implementation of 2D axisymmetric element is managed in Aster, so I don't know if any relations can be found for this bug between hexa 20 and quad 8.
