Hi Alan,

You are correct (although (1) is somewhat unclear - are we talking about Exodus files that have different element sets here?).

I would also recommend this document: http://www.vtk.org/Wiki/images/7/78/VTK-Quadrature-Point-Design-Doc.pdf which explains the current integration (gauss) point support. It doesn't do what he wants but it's worth a read.

Best,

A question from a user.  I believe that answer is correct to the first bullet, and the answer is no to the second bullet?


1 - Averaging a nodal result from surrounding elements is OK as long as the node is within a homogenous body.  This process is not correct for nodes on the boundary between two different materials.
2 - Is there a process to extrapolate element integration point quantities (stresses, strains) to nodes for elements with non-linear shape functions?


Thanks,

Alan
