[dune-fem] Lumping Quadrature for Lagrange

[Sacconi, Andrea]

Hi Claus,

I think it hasn't been implemented yet. I have been using this quadrature rule in my code for a while, implementing it myself. But if you discover its existence, let me know :-)

Cheers,
Andrea

Subject: [dune-fem] Lumping Quadrature for Lagrange

Hi,

another question: is there already a "lumping" quadrature for Lagrange
elements on simplex grids, i.e. a quad rule with weight 1/dim and
integration points at the vertices of a simplex? Its extremely simple to
implement, copying the code from dune/fem/quadrature/ but if it is
already there ... and yes, there are much more efficient ways to
implement mass-lumping, but ...

Best,

Claus
