\begin{itemize}
\item Real-time. We have 16--33 ms to compute everything.

+ \begin{itemize}
+ \item Supercomputer facilities are scarce resource.
+ \item Model basins are also scarce.
+ \item Without real-time visualisation we can not validate physics.
+ \item Regular workstations with a GPU can be used instead.
