Visualisation of quadrature point values
It would be nice to visualise the results of a finite element simulation, where the secondary quantities are computed at the quadrature points. As far as I am aware, these are handled by the user (extrapolated to nodes and averaged) but directly inspecting these values without extrapolation would be advantageous.
There is vtkQuadratureSchemeDefinition and friends but this seems to interpolate from the nodes to the quadrature points? Is it possible to plot a contour of these quadrature point values using VTK / ParaView?
I have gathered some relevant art, demonstrating some queries on this:
