\begin{itemize}
\item ex15 is an example which solves in parallel an operator using a finite
difference scheme. The diagonal is equals to 4 and 4 extra-diagonals
representing the neighbors in each directions is equal to -1. This example is
- used in many physical phenomena , for exemple, heat and fluid flow, wave

\item ex54 is another example based on 2D problem discretized with quadrilateral
finite elements. For this example, the user can define the scaling of material
