      * __"Home-SORMultigrid-ConstantMatrixCoef"__ : Successive Over-Relaxed method (SOR) coupled with a nV-cycle multigrid method in order to accelerate the convergence. The matrix elements depend on the cell size only (constant elements). This method is directly implemented in the code ("homemade" development). No external library is required to use it. The associated parameters are set in the namelist [[HomeData_PoissonSolver_Namelist |HomeData_PoissonSolver]] .
      * __"Home-HelmholtzApproximation"__ : Poisson's operator (constant matrix elements) is approximated by a Helmholtz's operator (experimental method proposed by J.L. Guermond) - For incompressible flow only. This method is directly implemented in the code ("homemade" development). No external library is required to use it. No parameter setting is needed.
-     * __"Home-PartialDiagonalization"__ : Partial diagonalisation of the Laplacian operator (constant elements). BEWARE : the problem must be separable. This method is directly implemented in the code ("homemade" development). No external library is required to use it. No parameter setting is needed.
+     * __"Home-PartialDiagonalization"__ : Partial diagonalisation of the Laplacian operator (constant elements). BEWARE : the problem must be separable. This method is directly implemented in the code ("homemade" development). External library Lapack and Blas is required to use it. The link must be specified in the makefile. No parameter setting is needed.
      * __"Home-SORMultigrid-VariableMatrixCoef"__ : SOR iterative method coupled with a multigrid method in order to accelerate the convergence. The matrix elements depend on the cell size and the density, the source term is defined from the divergence of the velocity. This method is directly implemented in the code ("homemade" development). No external library is required to use it. The associated parameters are set in the namelist [[HomeData_PoissonSolver_Namelist |HomeData_PoissonSolver]] .
      * __"Hypre-ConstantMatrixCoef"__ : Poisson's equation is solved by the HYPRE library tools. The matrix elements are constants. The parameters of the HYPRE library are set in the namelist [[HypreData_PoissonSolver_Namelist |HypreData_PoissonSolver]] .
