Efficient Entropy-Stable Discontinuous Spectral-Element Methods Using Tensor-Product Summation-by-Parts Operators on Triangles and Tetrahedra

Tristan Montoya, David W. Zingg

We present a new class of efficient and robust discontinuous spectral-element methods of arbitrary order for nonlinear hyperbolic systems of conservation laws on curved triangular…

Quadrature Rules on Triangles and Tetrahedra for Multidimensional Summation-By-Parts Operators

Zelalem Arega Worku, Jason E. Hicken, David W. Zingg

Multidimensional diagonal-norm summation-by-parts (SBP) operators with collocated volume and facet nodes, known as diagonal-E operators, are attractive for entropy-sta…
