PyAero Documentation

PyAero is a desktop tool for airfoil contour preparation, contour analysis, and 2D block-structured CFD meshing. The project focuses on the work that happens before the solver: turning raw airfoil coordinates into a clean working contour, refining point placement where it matters, generating a structured wind-tunnel mesh, and exporting the result in practical formats.

The application is written in Python, uses Qt for Python for the interface, and is distributed under the MIT license.

Example PyAero-generated mesh used in a downstream SU2 and ParaView workflow.

What PyAero Covers

• Load airfoils from the bundled library, a local library, or external contour files

• Prepare contours with CST or legacy B-spline workflows

• Refine leading-edge and trailing-edge point distributions

• Create finite-thickness trailing edges with independent upper and lower blending

• Inspect contour gradient, curvature, and radius plots

• Generate a structured C-type wind-tunnel mesh around the airfoil

• Smooth the mesh with simple, elliptic, or angle-based strategies

• Export meshes to .flma, .su2, .msh, and .vtu

• Export derived contour, camber, and CST data

• Prepare CFD helper inputs such as freestream components, wall distance, and turbulence values

• Run the same mesh-generation pipeline in batch mode

Notes

• PyAero currently focuses on 2D structured mesh generation and export.

• The export path is actively maintained; mesh import exists as future-facing scaffolding rather than a full workflow.

• The application should be started from the repository root so bundled resources resolve correctly.
