Those applications are available in the ksp part which is suited for scalable linear equations solvers: \begin{itemize} -\item ex15 is an example which solves in parallel a 2D homogeneous - Laplacian. Thediagonal 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 propagation... -\item +\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 propagation... +\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 coefficient in embedded circle, it is called $\alpha$. \end{itemize} - +For more technical details on these applications, interested reader are invited +to read the codes available in the PETSc sources. Those problem have been +chosen because they are scalable with many cores. We have tested other problem +but they are not scalable with many cores.
