Symmetry Preservation and Volume Consistency in an r-z Staggered Scheme
Original language description
This work is focused on the issue of symmetry preservation, energy and volume conservation and other important properties of staggered Lagrangian hydrodynamic schemes in cylindrical geometry. Typical advantages and drawbacks of existing area-weighted (AW) and genuinely r-z schemes will be pointed out. With quadrilateral cells it is known that, in r-z, spherical symmetry preservation, perfect satisfaction of GCL, and total energy conservation are incompatible. Being aware of this, we propose a staggeredapproach that conserves energy by construction and tries to do its best by diminishing the GCL error to the order of entropy error.
