The Aerothermodynamics Branch currently offers two software tools and a collection of supporting utilities.
NEQAIR – Nonequilibrium Radiative Transport and Spectra Program
NEQAIR is a line-by-line radiation code that computes spontaneous emission, absorption and stimulated emission due to transitions between various energy states of chemical species along a line-of-sight. NEQAIR v14.0 is a complex code that enables the calculation of: (1) Nonequilibrium or equilibrium populations of excited energy levels for atoms and diatomic molecules, (2) Optical radiation emitted and absorbed by atomic and diatomic rotational lines along a line-of-sight or across a shock tube, (3) Transport of optical radiation through a non-uniform gas mixture to a solid surface, and (4) Detailed spectra at points along a line-of-sight and at a surface.

Data Parallel Line Relaxation Code (DPLR)
The DPLR software package is a suite of CFD tools for the computation of supersonic and hypersonic flows in chemical and thermal nonequilibrium. Included in the package are 2D/axisymmetric and 3D structured grid finite volume Navier-Stokes codes, a pre-processor, and a post-processor. The code supports implicit boundary conditions, generalized multi-block topologies, grid alignment to shock envelopes, and generalized chemical kinetics and thermodynamic property databases.

CFD Utility Software Library
Computational Fluid Dynamics related FORTRAN libraries and applications. Comprised of mostly single-function tools for manipulating multiblock grids and flow solutions. Provides rapid searching and interpolation for structured or unstructured grids.
