MACH-Aero Framework

MACH-Aero is a framework for performing gradient-based aerodynamic shape optimization. It consists of the following core modules:

• baseClasses defines Python classes used by the other packages

• pySpline is a B-spline implementation used by the other packages

• pyGeo is a module for geometry manipulation and constraint formulation

• IDWarp performs mesh warping using an inverse distance method

• ADflow is a 2nd-order finite volume CFD solver with an efficient adjoint implementation

• pyOptSparse is an optimization framework which provides a unified interface to several popular optimizers

And the following optional modules:

• pyHyp is a hyperbolic mesh generation tool used as a preprocessing step

• multiPoint facilitates distributed multipoint optimization and handles the parallel communication using MPI

• cgnsUtilities is a command-line tool that allows carrying out several simple mesh manipulation operations on CGNS grids

• DAFoam provides efficient adjoint implementations for OpenFOAM to be used for CFD instead of ADflow

More detail for the framework can be found in Overview of MACH-Aero. If you use any of our codes, please cite us. If you would like to contribute to the development of any of these packages, please see our contribution guide.
