In this paper, the movement of the water surface with macroscopic particles during a dam break flow using the volume of fluid (VOF) methods, the discrete phase model (DPM) and macroscopic particle model (MPM) models were numerically simulated. To solve this equation system numerically, the piso numerical algorithm was chosen. The accuracy of the 3D model and the selected numerical scheme were tested using some laboratory measurements on the destruction of the dam break problem. In the test problem, the values were matched with measurement values and simulation data of other authors. Furthermore, two problems were also considered, the first problem is dam break flow with macroscopic particles, and the second problem - water movement with macroscopic particles, through a heterogeneous terrain and a dam that has a hole. With the help of the problems, the flooding zones and the time of flooding evacuating people from dangerous areas were determined.

In the present study we consider the parallel simulation on a peer-to-peer demonstrator for the computation of a 3D differential equations, which model the behavior of the continuous-flow electrophoresis problem. The physical model considered is constituted by the Navier-Stokes equation coupled with a convection-diffusion equation and a Laplacian equation. By using appropriate discretization of the coupled boundary value problems, we can prove the convergence of synchronous and more generally asynchronous relaxation methods. Finally parallel experiments on the peer-to-peer demonstrator are presented and analyzed.

This paper deals with the implementation on the GRID' 5000 network, the French grid platform, of parallel simulations for the solution of a 3D coupled boundary value problem of continuous flow electrophoresis which is governed by Navier Stokes equations coupled with convection-diffusion and potential equations. The coupled boundary value problems are discretized by appropriate schemes involving the convergence of the parallel synchronous and asynchronous Schwarz alternating algorithms. Finally, parallel experiments on grid computing are presented and analysed.
