Description:Fluid dynamics, numerical modelling
Abstract:The computational fluid dynamics (CFD) provide general methods for solving wide range of actual applications in the wide areas of engineering. Many important industrial problems include convective transport, viscous incompressible flows governed by the Navier-Stokes equations, moving interfaces and coupled problems. Sluice gates, dam break flows, tank sloshing, sediment and pollution transport has been modelled by the developed software FEMTOOL. The main part of the software is parallel iterative algorithms for solving large systems of linear equations obtained modelling various problems of Computational Fluid Dynamics. The parallelization of the code is based on the domain decomposition. The mesh partitioning is performed by METIS. The systems of linear equations are solved by the iterative Generalised Minimal Residual solver (GMRES).
FEMTOOL source code is academical and open source. Code is written using Fortran 77 language, MPI and ATLAS libraries are included. Minimal requirement for the processor is Intel Pentium 3.2 Mhz, 1GB RAM. Recommended amount of disk space for data is 1GB. Software is communication intensive, so minimal bandwidth between WN must be 1 Gbps. FEMTOOL is integrated with Migrating Desktop. Grid visualization e-service VizLitG is used for visualization of computed results.
