内容記述 | A pointwise relaxation implicit Discontinuous Galerkin (DG) method developed in our study is extended to unstructured hybrid grids comprised of hexahedral, pyramidal, prismatic and tetrahedral cells. The mathematical formulation of the present method is first shown. The scalar advective equation in 3D space is then solved using hybrid grid. The accuracy of the scheme as well as the convergence rate is examined for illustrating the characteristics of the present numerical method. Finally, the pointwise relaxation implicit DG method for 3D Euler equations is constructed to solve inviscid compressible flowfield over ONERA-M6 isolated wing using hybrid mesh systems. | |||||
