Function Documentation

Metric* gridripper::metric::createMetric ( const std::string &  name,
const MetricParam &  params 
)

Create a metric.

The name "MInert" will index Minkowski metric in $\tau:=t$ (inertial time), $\rho:=\frac{\sqrt{\kappa^2 r^2+1}-1}{\kappa r}$ (compactified radius) coordinates, where $t$ is an inertial time, and $r$ is an inertial radius, and $\kappa$ is a compactification parameter.

The name "MHyper" will index Minkowski metric in $\tau:=\kappa t-\sqrt{\kappa^2 r^2+1}$ (hyperbolic time), $\rho:=\frac{\sqrt{\kappa^2 r^2+1)-1}}{\kappa r}$ (compactified radius) coordinates, where $t$ is an inertial time, and $r$ is an inertial radius, and $\kappa$ is a compactification parameter.

The name "Sch" will index Schwarzschild metric in $\tau:=\frac{1}{\sqrt{X^2+1}-T}$, $\rho:=\frac{\sqrt{\kappa^2 X^2+1}-1}{\kappa X}$ coordinates, where $T$ and $X$ are the Kruskal-Szekeres coordinates, and $\kappa$ is a compactification parameter. $M$ is Schwarschild mass.
