High-Order Mesh Generation for Discontinuous Galerkin Methods Based on Elastic Deformation
Published online by Cambridge University Press: 27 May 2016
Abstract
In this paper, a high-order curved mesh generation method for Discontinuous Galerkin methods is introduced. First, a regular mesh is generated. Second, the solid surface is re-constructed using cubic polynomial. Third, the elastic governing equations are solved using high-order finite element method to provide a fully or partly curved grid. Numerical tests indicate that the intersection between element boundaries can be avoided by carefully defining the elasticity modulus.
