Programming language: Fortran 90 and OpenMPI
Computer: All shared or distributed memory parallel processors, tested on a Xeon W3520, 2.67 GHz.
Operating system: Any system with a Fortran 90 compiler and MPI, tested on Debian Linux.
Has the code been vectorised or parallelised?: The code has been parallelised but has not been explicitly vectorised.
RAM: Dependent upon the number of particles.
Classification: 4.12
Nature of problem: JOSEPHINE is designed to solve unsteady incompressible flows with a free-surface and large deformations.
Solution method: JOSEPHINE is an implementation of Smoothed Particle Hydrodynamics. SPH is a Lagrangian mesh free particle method, thus, no explicit tracking procedure is required to catch the free surface. Incompressibility is satisfied using a weakly compressible model. Boundary conditions at walls are enforced by means of the ghost particles technique. The free-surface dynamic and kinematic conditions are applied implicitly.
Running time: 15 mn on 4 processors for the dam-break case with 5000 particles, dependent upon the real duration (2 s here).
