High order entropy
WebJul 25, 2024 · Similar entropy conservative/stable numerical fluxes were adopted in the high-order nodal DG literature, which, in combination with discrete derivative operators using Gauss-Lobatto quadrature points that satisfy the summation-by-parts (SBP) property, yield entropy conservative/stable DG discretizations [ 24, 45, 46 ]. WebEntropy is not energy; entropy is how the energy in the universe is distributed. There is a constant amount of energy in the universe, but the way it is distributed is always changing.
