That method lets you conveniently access all the elements sharing a given node, which is not what you want in this case.
The usual way to do this is by solving an L2 projection onto a continuous field - think of this as finding the continuous gradient field that best approximates your discontinuous field in a least-squares sense. I don't think there are any examples that currently show this - I'll try to add one after the next release. Given that it is a common-enough post processing task, we might start a discussion on the development list as to how to best provide this as a core library service... -Ben On Oct 29, 2012, at 3:41 AM, "Subramanya Gautam Sadasiva" <ssada...@purdue.edu> wrote: > Hi, > I need to extrapolate element fields to the nodes in order to compute > approximate gradients for some quantities defined at the quadrature points. > What is the easiest way to accomplish this? > I saw meshtools has a nodes to elem map function.Does this work for parallel > meshes? > Thanks. > Subramanya > > ------------------------------------------------------------------------------ > The Windows 8 Center - In partnership with Sourceforge > Your idea - your app - 30 days. > Get started! > http://windows8center.sourceforge.net/ > what-html-developers-need-to-know-about-coding-windows-8-metro-style-apps/ > _______________________________________________ > Libmesh-users mailing list > libmesh-us...@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/libmesh-users ------------------------------------------------------------------------------ The Windows 8 Center - In partnership with Sourceforge Your idea - your app - 30 days.
