 ==== A brief Description of SUNFLUIDH ====
+[[:start|Click here to come back to the previous page]]
-SUNFLUIDH is a computational software developped by Yann Fraigneau at LIMSI in order to maintain the know-how of the lab in terms of numerical methods development and to be able to respond to the needs of the searchers in the domain of computational fluid dynamics.
-A brief description of the computational software is here presented. More details are provided in the documents that can be downloaded [[ https://p2i.limsi.fr/p2i:logiciels:logiciels_limsi_meca | here ]].

 === Geometries ===
-The geometrical configurations mainly rely on a cartesian topology as the mesh is restricted to an orthogonal strutured form. It is however possible to define complex geometries by means of immersed bodies wich modelize solid parts.

 The projection method implies a Poisson's equation that can be solved with different methods :
      * The partial diagonalisation of the laplacian operator (a direct method suitable for separate problems only)
-     * The Relaxed Gauss-Seidel method couled with a muti-grid approach in order to accelerate the convergence (an iterative method applicable for any problem)

 This last method can be used for different formulations of the Poisson equation :\\
-    * $\nabla\frac{1}{\rho}\nabla \phi=S$ where S is proportional to the divergence of the momentum.\\
+    * $\nabla\frac{1}{\rho}\nabla \phi=S$ where S is a function of the divergence of the momentum.\\
-    * $\Delta \phi = S$  where S is proportional to the divergence of the velocity.
+    * $\Delta \phi = S$  where S is a function of the divergence of the velocity.
