- W2057059969 abstract "Abstract Spherically symmetric perfect fluid configurations in general relativity are modelled using finite element discretizations for the radial direction and finite difference discretizations for the temporal direction. The equations are derived from a variational principle based on a Schwarschild-like metric and the relativistic enthalpy for a perfect fluid. A simple explicit two-step scheme is used in time, and the weighted residual method with various spline approximations radially. The linear spline approximation is successful, but does have an instability which becomes serious during the later stages of an evolution. Cubic Hermite splines are more stable, but the velocity near the surface shows instabilities. A special cubic Lagrange approximation for the velocity, and Hermite approximations for the other variables, proves the best scheme, but it is still necessary to introduce some smoothing algorithm near the surface." @default.
