Three-dimensional panel method for low-speed aerodynamics
Structured mesh generation: Lofts • Bodies of revolution • User-defined space transformations
Unstructured mesh import: OpenVSP • CAD (e.g., SolidWorks) + Gmsh • Meshes.jl
Multi Element: Source-panel or doublet/vortex-ring for non-lifting bodies • Doublet/vortex-ring for lifting bodies with rigid wake model
Flexible Solver: Direct LU decomposition • Iterative Krylov (GMRES) • Handling of both watertight and open meshes • Multiple bodies
Fast Computation: GPU enabled • CPU threaded • Low memory allocation • Type stable • Adjoint solver through ImplicitAD for gradient-based optimization • Support for both ForwardDiff and ReverseDiff
Current Limitations: Inviscid (no viscous drag nor stall) • Incompressible • No fast multipole method (though a 30,000 panel problem can still be solved in as fast as 90 seconds on a laptop)
Coded in the Julia language for Linux, MacOS, and Windows WSL.
