HAVA-STABLX1
Stability solver for compressible flows that maps how small disturbances grow or decay and where transition-sensitive regions appear.
HAVA-STABLX1 is a GPU-accelerated stability solver for compressible flows, built to study how small disturbances evolve and where transition-sensitive regions appear. It evaluates stability behavior across Mach number, Reynolds number, disturbance frequency and streamwise wavenumber ranges, producing clear maps of growth and decay trends.
By tracking the dominant instability modes, including Tollmien–Schlichting and Mack modes, HAVA-STABLX1 helps identify unstable regions, compare flow regimes and investigate high-speed flow transition with greater speed and consistency. Its GPU acceleration makes it well suited for large studies that need many repeated stability evaluations while keeping reliable, high-resolution results.
Extensive validation and verification studies are ongoing.
