Positivity-Preserving and Entropy-Stable Oscillation-Eliminating DGSEM for the Compressible Euler Equations on Curvilinear Meshes with Adaptive Mesh Refinement
Jielin Yang, Jieling Yang, Guosheng Fu
We extend the entropy-stable oscillation-eliminating discontinuous Galerkin spectral element method (ES-OEDG) on curvilinear meshes \cite{YangFu26} to adaptive mesh refinement (AMR…

An entropy-stable oscillation-eliminating dgsem for the euler equations on curvilinear meshes
Jielin Yang, Guosheng Fu
We develop an entropy-stable high-order numerical method for the two-dimensional compressible Euler equations on general curvilinear meshes. The proposed approach is based on a nod…
