More than visualization, I need to be able to associate sensitivities with spatial locations for uncertainty propogation. I can do this via the GMV/Exodus route but was looking for a more direct route via libMesh. On Wed, Feb 11, 2015 at 8:49 PM, Roy Stogner wrote: > > "Does not compute" is righ

"Does not compute" is right in general. DoFs don't have locations, they have functionals, and it's only in the Lagrange case that those functions are delta functions at particular locations. You were asking me about adaptive p refinement recently, and one thing I forgot to mention is that libMes

That question doesn't compute. Do you mean get the xyz position of the node associated with a Lagrange DoF? On Wed Feb 11 2015 at 8:25:57 PM EST Vikram Garg wrote: > Can someone tell me how one can obtain the xyz coordinates corresponding to > a global dof id ? > > Thanks. > -- > Vikram Garg >
