HArD::Core2D
Hybrid Arbitrary Degree::Core 2D - Library to implement 2D schemes with edge and cell polynomials as unknowns
|
The vector Xh manipulated in the resolution has mixed components, corresponding either to the unknown u or to \(\zeta(u)\), depending on the choice of weight of mass-lumping for the cell/edge unknowns. If no weight is put on the edges (resp. the cells), then the edge (resp. cell) unknowns represent \(\zeta(u)\). Otherwise, they represent u. More...
