Positivity-preserving hybrid DG/FV method for compressible Euler equations with stiff source terms
Zhen-Hua Jiang, Xi Deng, Lin-Tao Huang +3
In numerical simulations of complex fluid dynamical problems, unphysical negative density or pressure may appear, causing blow-up of the computation. With the aim of obtaining posi…
