[GiDlist] questions about the results on gauss points of hex
Posted: Thu Nov 21, 2002 12:09 pm
I have some questions about the postprocessing with results on the gauss points using gid version 7.1.3. b
1) In the attached file "prova1" I have put the gauss points coordinates in a different order respect the internal order of gid and I in the contour visualization of the scalar result I can see only the gauss points and not the whole solid . Why?
2) In the file "prova2" I have put the gauss points coordinates in the same order of the internal one and I in the contour visualization of the scalar result I see some problem around the nodes. (in this case the scalar result is the same for all the 8 gauss points)
3) In the file "prova3" I have put the gauss points coordinates in the same order of the internal one and the scalar result is not the same for all the 8 gauss points. In this case the contour visualization of the scalar result seems to be right.
4) I think that gid do a local smoothing of the results from the gauss points to the nodes and then do a mean of the results coming from all the elements converging in the same node . This average value has not meaning if the elements converging in the node have different material properties . In this case is better that the finite element code do the local smoothing?
