论文部分内容阅读
　　When curved boundaries are present,in general schemes defined on a conforming mesh should be used towards high order accuracy.For a 2D problem,given a straight-sided triangular geometry-fitting mesh,DG scheme using polynomials of high degrees will be only second order accurate.We discuss a simple modification to DG schemes defined on straight-sided triangles to recover the high order accuracy,as an alternative to the full curvilinear DG method.
