CFDWARP is a in-house-developed 200K-line C code that simulates efficiently plasma and reactive flows occurring in aerodynamics, combustion, hypersonics, planetary entry, semiconductor manufacturing, and magnetohydrodynamics (MHD). CFDWARP is a multi-block structured mesh compressible flow solver that uses high-order flux discretization schemes suitable for Reynolds-averaged Navier-Stokes (RANS) and Implicit Large Eddy Simulation (ILES). CFDWARP is superior to other codes in being capable to integrate the electron and ion equations along with the bulk flow equations using aerodynamic-scale (i.e. microsecond and higher) integration steplengths, permitting the simulation of non-neutral plasmas in about the same amount of computing effort as non-ionized reactive flows (see https://doi.org/10.2514/1.J054624).
