A general framework to construct schemes satisfying additional conservation relations. Application to entropy conservative and entropy dissipative schemes
R Abgrall - Journal of Computational Physics, 2018 - Elsevier
We are interested in the approximation of a steady hyperbolic problem. In some cases, the
solution can satisfy an additional conservation relation, at least when it is smooth. This is the …
