 r5619 \begin{equation} \delta t = \min_{k,i=[0,1,2]}  r_k/v_i \Delta t = \min_{k,i=[0,1,2]}  \min(\frac{r_k}{v_{k,i}}, \fract{r_{n_{k,i}}}{v_{k,i}} \label{eq:CFL condition} \end{equation} where $r_k$ is the radius of the $k$th triangle and $v$ is the maximal velocity across the edge joining triangle $k$ and it's neighbour triangle $i$ as calculated by the numerical flux function using the central upwind scheme of \cite{KurNP2001}. where $r_k$ is the radius of the $k$'th triangle and $v_{k,i}$ is the maximal velocity across edge joining triangle $k$ and it's $i$'th neighbour, triangle $n_{k,i}$, as calculated by the numerical flux function using the central upwind scheme of \cite{KurNP2001}. The symbol $r_{n_{k,i}}$  denotes the radius of the $i$'th neighbour of triangle $k$. The radii are calculated as radii of the inscribed circles of each triangle. \section{Flux limiting}
