Section: New Software and Platforms


Aironum is an experimental software that solves the unsteady compressible Navier-Stokes equations with k-, LES-VMS (Large Eddy Simulation - Variational Multi-Scale) and hybrid turbulence modelling on parallel platforms, using MPI. The mesh model is unstructured tetrahedrization, with possible mesh motion.

Aironum was developed by Inria and University of Montpellier. It is used by Inria, University of Montpellier and University of Pisa. 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 (Reynolds Averaged Navier-Stokes) statistical models.
