maia

MAIA is a multi-physics PDE solver framework with a focus on fluid dynamics equations. It is developed at the Institute of Aerodynamics of the RWTH Aachen University in Germany.

Quickstart

1. Clone this repository
   • Run git clone git@git.rwth-aachen.de:aia/MAIA/Solver.git
   • Or directly with its submodules git clone git@git.rwth-aachen.de:aia/MAIA/Solver.git --recurse-submodules
2. Run ./configure.py ? ? in the top directory.
3. Run make
4. Execute a setup using ./maia #property_file

Build and view the documentation

1. Clone this repository
2. Run /configure.py ? ? in the top directory.
3. Run make doc. This will take a few minutes since the whole code is scanned using Doxygen.
   • Or run the fast compilation with make doc-fast to scan only the doc-folder for any changes.
4. Open the file doc/documentation.html in a web browser.

Start developing

1. Create a private fork.
2. Implement/Improve/Fix something.
3. Create a merge request.
   1. Include a complete canary report with your merge request.
4. Wait for approval of your changes.

Installing

Prerequisites

Automatic configuration files are provided for:

• AIA
• JUWELS (Forschungszentrum Juelich)
