Hello everyone, I have a discontinuous velocity field composed of FE_DGQ elements; I would like to access a modal representation of the solution coefficients on each element and modify them (e.g., to perform slope limiting).
I was planning on - manually constructing the Vandermonde matrix on each element to convert the solution representation to a modal one - modifying the solution coefficients - transforming them back to a nodal representation - updating the entries in the global solution vector Is there a better way of doing this? I want to make sure I'm not reinventing the wheel in the event that this functionality is already implemented. I was looking at the documentation for FE_DGP but it seems that these elements may not span the same space as their corresponding nodal counterparts of the same polynomial order, and the two finite element objects are not necessarily meant to be used in conjunction (for example, by defining two FEValues objects with FE_DGP and FE_DGQ finite elements and a nodal quadrature rule).
