    gsIF - software for incompressible turbulent fluid flow simulation based on isogeometric analysis

  • Original language description

    Software implements numerical solving of steady and unsteady Navier-Stokes equations and RANS (Reynolds-Averaged Navier-Stokes) equations complemented with k-omega SST turbulent model in 2D and 3D complex computational domains by the so-called isogeometric analysis. Computational domains and meshes can be represented by B-spline/NURBS objects which are standard objects used for representation of complex objects in modern CAD/CAM systems. The software allows to use boundary conditions, which are available in other softwares for computational fluid dynamics, such homogeneous and non-homogeneous Dirichlet boundary conditions, homogeneous Neumann boundary condition or periodic boundary conditions. As this software is meant to be used mainly for turbulent flows, it also allows to use wall functions. Moreover, for simulation of the incompressible turbulent fluid flow being one o the most computationally demanding simulations, the simulations solved by this software can be run in parallel where parallelization is handled by MPI (Message Passing Interface). Thus, large computational systems with distributed memory can be exploited with this software. The software gsIF is implemented in C++ as an optional package for the library G+Smo.
