Hello, The class UnstructuredGrid was implemented by me some 2 years ago as an experimental version. The behavior you described was used on purpose, as it was very simple and worked at that time (at least if I remember correctly).
I will have a look on the code and let you know if/what I will modify it. cheers Jan 2015-06-05 2:38 GMT+02:00 MikeZhao <[email protected]>: > New question #267761 on Yade: > https://answers.launchpad.net/yade/+question/267761 > > I am working on renewing coordinates of Facet using function > :setPositionsOfNodes and updateElements in yade.utils module and I have > found out that there's something wrong with these functions. > > The position of Facet is illustrated with a reference position and a local > coordinate, as is defined in the yade.utils module.
