Compatible , Energy and Symmetry Preserving 2 D Lagrangian Hydrodynamics in rz - Cylindrical Coordinates LA - UR 09 - 08130
We present a new discretization for 2D Lagrangian hydrodynamics in rz geometry (cylindrical coordinates) that is compatible, energy conserving and symmetry preserving. Although this formulation can be used for general polygonal meshes, we only describe it for a logically rectangular grid in this paper. We show that our discretization preserves spherical symmetry on polar equiangular meshes. The...
متن کاملPositivity-preserving and symmetry-preserving Lagrangian schemes for compressible Euler equations in cylindrical coordinates
For a Lagrangian scheme defined in the cylindrical coordinates, two important issues are whether the scheme can maintain spherical symmetry (symmetry-preserving) and whether the scheme can maintain positivity of density and internal energy (positivity-preserving). While there were previous results in the literature either for symmetry-preserving in the cylindrical coordinates or for positivity-...
متن کاملSecond order symmetry-preserving conservative Lagrangian scheme for compressible Euler equations in two-dimensional cylindrical coordinates
In applications such as astrophysics and inertial confine fusion, there are many threedimensional cylindrical-symmetric multi-material problems which are usually simulated by Lagrangian schemes in the two-dimensional cylindrical coordinates. For this type of simulation, a critical issue for the schemes is to keep the spherical symmetry in the cylindrical coordinate system if the original physic...

متن کاملSPH in spherical and cylindrical coordinates
New kernel functions for spherically, planar and cylindrically symmetric problems are developed, based on the fundamental interpolation theory of SPH. The Lagrangian formalism is used to derive the corresponding set of modified SPH equations of motion. The results show good agreement both with analytical and numerical results, in the case of the Sod shock tube test, the Noh infinite shock probl...
