Possibly use ENO interpolation. Useful e.g. for hydro where shocks may appear.
To make Cartoon use the ENO interpolator you need an additional tags table entry. The same tags are used as for Carpet. Either
tags='Prolongation="TVD"'
or
tags='Prolongation="ENO"'
will work.
The default (i.e., with no tag) is to use the standard Lagrange polynomials. The tags "Lagrange" and "None" will also do this. Also, any direct call to the Cartoon functions (BndCartoon2DVI etc.) will use Lagrange interpolation.
Code from Burkhard Zink for interpolation; tags table stuff from me.
