| Parallel computing | FEST-3D uses MPI to distribute computation across processors on one or more machines. | The simulator is intended to run on Linux clusters and supports MPI; the docs describe testing with Open MPI and MPICH on Linux and macOS, and MS-MPI on Windows. |
| Purpose | FEST-3D is a Fortran 90 finite-volume solver for Navier–Stokes equations on structured grids, developed for aerodynamic flow problems. | pyuvsim is a Python package for accurate, extensible radio interferometer simulations, with a focus on precision needed for 21 cm cosmology. |
| Support | The homepage lists [email protected] as the project contact email. | Users are directed to the GitHub issue log for questions, bug reports, and feature requests. |

In their own words
FEST-3D
FEST-3D is a Fortran 90 finite-volume computational fluid dynamics solver for Navier–Stokes flow problems on structured grids, developed for aerodynamics. It handles incompressible and compressible flows, including inviscid, laminar, transitional and turbulent cases. Users can select among flux schemes, reconstruction methods, time-integration options, turbulence models and transition models. MPI distributes computations across processors on one or more machines. The solver is free and open source under the GNU General Public License version 3.0, with source available from GitHub. Its installation script supports Ubuntu/Debian, CentOS and macOS, while manual installation instructions cover Linux. Building requires a Fortran compiler, an MPI library, CMake and Make. Tutorials in a separate repository address verification cases such as a smooth bump, lid-driven cavity, flat plates and an airfoil. FEST-3D writes VTK or Tecplot output for separate visualization tools. Grid generation and post-processing are outside the solver, and the project notes its halt/stop condition does not work with MPI.
