2.4.1 Parameter of the following examples

Boundary conditions influence the properties of real world hydrodynamic flows.

Linear 1D advection: infinite domain without boundaries.

Actual implementation of boundary conditions in numerical experiments:

Grid settings:

i_\mathrm{total}=200 \enspace , \enspace
... x} = 0.4 \enspace \Rightarrow \enspace
\mbox{one revolution}
\end{displaymath} (109)

Initial condition: ``spikes'' (Gaussian, rectangle, triangle, half-ellipse), see Jiang & Shu (1996).
