MachLine (Multi-order Approach to Calculating High-speed Linear Aerodynamics) is a modern, unstructured, subsonic/supersonic flow solver currently being developed by the AeroLab at Utah State University. It is a linear panel method based on the Prandtl-Glauert equation. MachLine will implement many features not available in legacy compressible panel methods, such as unstructured meshes, iterative matrix solvers, automatic wake modelling, variable-order singularity distributions, and more.

MachLine is under active development. We anticipate development to be completed sometime in the summer of 2023. Already, MachLine has been thoroughly vetted against PAN AIR and experimental data.

Wondering where to begin? Getting Started is a great place to go for new users. Modeling will describe a lot of the high-level aspects of using MachLine. Capabilities will list for you the current capabilities of MachLine.
