Re: [Libmesh-users] Averaging element fields to the nodes.

2012-10-29 Thread Kirk, Benjamin (JSC-EG311)
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 disconti

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. Subraman
