AIRONUM

Participant : Alain Dervieux [correspondant] .

aironum is an experimental software that solves the unsteady compressible Navier-Stokes equations with $k-ϵ$, LES-VMS and hybrid turbulence modelling on parallel platforms with MPI as parallel programming concept. The mesh model is unstructured tetrahedrization, with possible mesh motion. See also http://www-sop.inria.fr/tropics/aironum

• Version: v 1.0

• Programming language: Fortran95 (mostly). About 100,000 lines.

aironum was developed by Inria and university of Montpellier. It is used by Inria, university of Montpellier and university of Pisa (I). aironum is used as an experimental platform for:

• Numerical approximation of compressible flows, such as upwind mixed element volume approximation with superconvergence on regular meshes.

• Numerical solution algorithms for the implicit time advancing of the compressible Navier-Stokes equations, such as parallel scalable deflated additive Schwarz algorithms.

• Turbulence modelling such as the Variational Multiscale Large eddy Simulation and its hybridization with RANS statistical models.
