INCA is a general-purpose multi-physics Computational Fluid Dynamics (CFD) solver for high-fidelity Direct Numerical Simulation (DNS) and Large Eddy Simulation (LES). Its main application fields are turbulence research and aerospace engineering.
Adaptive Methods for Complex Geometries
- Automatic mesh generation and dynamic adaptation (AMR) with pre-implemented or user-defined criteria.
- Geometry from CAD software or structure dynamics solvers.
- Conservative cut-cell immersed boundary methods (IBM) with sub-cell resolution for fluid-solid and fluid-fluid interfaces.
- Coupling of IBM to finite element methods (FEM) and reduced order models (ROM) for fluid structure interaction (FSI).
- Arbitrary (inertial or non-inertial) frame of reference.
Multi Physics and Weird Materials
- Compressible and incompressible flows of inert and chemically reacting fluids.
- Accurate state and transport properties for dense (supercritical) and dilute multi-species mixtures.
- Multiphase thermodynamics (cavitation, boiling, evaporation, condensation, etc.).
- Thermochemical non-equilibrium and gas-solid interactions such as ablation.
Turbulence
- High-order fully-conservative methods for DNS.
- The 13 most popular functional and structural SGS models for traditional explicit LES.
- Implicit LES methods based on reinforcement learning of turbulence theory - physical, mathematical and numerical modeling in a unified framework.
- Wall models facilitate LES of high Reynolds number engineering flows.
High Performance Numerics
- Massively parallel (MPI and OpenMP), high performance computing on thousands of processors.
- 19 parallelized solvers for linear and linearizable problems.
- 13 time-integration schemes, >60 discretization methods for hyperbolic equations, etc.
