The record

Purpose: FEST-3D is a Fortran 90 finite-volume computational fluid dynamics solver for Navier–Stokes flow problems on structured grids, developed for aerodynamics.
Open source: FEST-3D is available under the GNU General Public License version 3.0.
Flow types: The solver handles incompressible and compressible, inviscid, laminar, transitional, and turbulent flow problems.
Numerical schemes: It offers multiple inviscid flux, higher-order face reconstruction, time-integration, turbulence, and transition model options.
Parallel computing: FEST-3D uses MPI to distribute computation across processors on one or more machines.
Downloads: The solver source is available from GitHub, and tutorials are in a separate repository included as a source-code submodule.
Installation platforms: The installation script supports Ubuntu/Debian, CentOS, and macOS; manual installation instructions are provided for Linux platforms.
Dependencies: The documented build dependencies include a Fortran compiler, an MPI library, CMake, and Make.
Tutorials: Provided verification tutorials cover ramp and smooth-bump flows, a lid-driven cavity, flat-plate flows, and a transonic RAE-2822 airfoil.
Grid generation: Grid generation is separate from the solver and must be handled independently; the documentation suggests writing a grid-generation program or using software such as Pointwise for complicated geometries.
Visualization: The solver writes VTK or Tecplot output, and the documentation names VisIt, ParaView, and Tecplot as tools for visualizing results.
Notable limitations: The homepage reports that the halt/stop condition does not work on MPI and turbulent simulations cannot run on Windows Subsystem for Linux because of outdated OS and libraries.
Support: The homepage lists [email protected] as the project contact email.
Intended users: The project describes its team as students from the Department of Aerospace Engineering at IIT Madras, and its tutorials are provided for learning and verification.
