“…As the global mass matrix is diagonal, its inversion is an easy process. The size of the global vector of unknowns is optimized by the use of an expert multigrid system called AMS (see [7] and [8]). On the whole, a high performance level is obtained both in terms of CPU and storage costs.…”

A Finite Element Method using a C++ code is developed to study the mechanical wave propagation in saturated porous soils. The modelization uses the complete Biot theory including the couplings between the solid and fluid phases. A matrix-free algorithm and a selection data technique are implemented in the code. Researches are focused on homogeneous and heterogeneous semi-infinite media in the case of transient regimes. The time domain results present the displacements over and within the half-space. In particular, we will see that the fluid wave front is strongly dependent on the proportion of heterogeneities in the ground.

“…We use efficient C++ Object-Oriented Programming for the Finite Element code called FAFEMO (Fast Adaptive Finite Element Modular Object) [4]. In practice, three objects compose a solver and they are separated in three source files.…”

“…Among different hardware concepts the SIMD  Single Instruction Multiple Data  architecture has proved to be the most promising for parallel computers. This technology is used for high performance computing especially when problems such as solving large sets of differential equations are dealt with [4]. A SIMD parallel computer consists of a set of processors connected with a fast communication network.…”

We have developed a coherent set of techniques for parallel computing. We have used the Finite Element Method associated with the C++ Object-Oriented Programming with only one database. A technique of data selection is used in the determination of the data dedicated to each processor. This method is performed by SIMD technology associated with MPI capabilities. This parallel computing is applied to very large CPU cost problems particularly the unsteady problems or steady problems using iterative methods. Different results in Computational Fluid Dynamics are presented.
