A panel-based flow solver. Currently in beta but with working solvers for incompressible and inviscid hypersonic flow.
Discrete vortex panel method
Calculate common 2D airfoil parameters by just setting a few inputs and drawing the geometry of the body in a dynamic way
Industrial aerodynamics case study predicting laminar-to-turbulent boundary-layer transition over a 3-D natural-laminar-flow aircraft wing (AETHER-NLF 25), using the UTSS multi-mechanism transition solver — includes geometry, mesh, solver outputs, figures, experimental validation, and the full report.
Find the NACA 4-digit airfoil that meets your target: minimum drag at a given lift, or maximum lift under a drag limit. Two solvers, same workflow: an in-house panel method and XFOIL. Exports data and geometry for CAD and CFD.
Panel-based boundary integral equation solver for 2D Laplace problems using Nyström discretization.
Panel method solver and UI application with Streamlit
🛠️ Build and run XFOIL 6.99 for airfoil analysis on macOS Apple Silicon with patched source and GUI support via XQuartz.
