Facts

Purpose
FEST-3D is a Fortran 90 finite-volume computational fluid dynamics solver for Navier–Stokes flow problems on structured grids, developed for aerodynamics.fest3d.github.io · 4 Oct 2026
Open source
FEST-3D is available under the GNU General Public License version 3.0.fest3d.github.io · 4 Oct 2026
Flow types
The solver handles incompressible and compressible, inviscid, laminar, transitional, and turbulent flow problems.fest3d.github.io · 4 Oct 2026
Numerical schemes
It offers multiple inviscid flux, higher-order face reconstruction, time-integration, turbulence, and transition model options.fest3d.github.io · 4 Oct 2026
Parallel computing
FEST-3D uses MPI to distribute computation across processors on one or more machines.fest3d.github.io · 4 Oct 2026
Downloads
The solver source is available from GitHub, and tutorials are in a separate repository included as a source-code submodule.fest3d.github.io · 4 Oct 2026
Installation platforms
The installation script supports Ubuntu/Debian, CentOS, and macOS; manual installation instructions are provided for Linux platforms.fest3d.github.io · 4 Oct 2026
Dependencies
The documented build dependencies include a Fortran compiler, an MPI library, CMake, and Make.fest3d.github.io · 4 Oct 2026
Tutorials
Provided verification tutorials cover ramp and smooth-bump flows, a lid-driven cavity, flat-plate flows, and a transonic RAE-2822 airfoil.fest3d.github.io · 4 Oct 2026
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.fest3d.github.io · 4 Oct 2026
Visualization
The solver writes VTK or Tecplot output, and the documentation names VisIt, ParaView, and Tecplot as tools for visualizing results.fest3d.github.io · 4 Oct 2026
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halt/stop condition does not work on MPI and turbulent simulations cannot run on Windows Subsystem for Linux because of outdated OS and libraries.fest3d.github.io · 4 Oct 2026
Support
The homepage lists [email protected] as the project contact email.fest3d.github.io · 4 Oct 2026
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.fest3d.github.io · 4 Oct 2026
Solver structure
FEST-3D is a modular, multiblock solver and supports computations distributed across processors using MPI.fest3d.github.io · 5 Oct 2026
Numerical methods
Available options include AUSM-family and SLAU flux schemes, MUSCL, PPM and WENO spatial reconstruction, and explicit and implicit time integration.fest3d.github.io · 5 Oct 2026
Flow models
The documentation lists SA, SST, SST2003 and k-kL turbulence models, plus Gamma LCTM2015 and SA-BC transition models.fest3d.github.io · 5 Oct 2026
Supported installation platforms
The installation script is provided for Ubuntu (Debian), CentOS and macOS; manual installation instructions are provided for Linux.fest3d.github.io · 5 Oct 2026
Visualization integrations
The solver can output VTK or Tecplot files for viewing with tools such as VisIt, ParaView or Tecplot; post-processing is outside the solver.fest3d.github.io · 5 Oct 2026
Grid generation limit
Grid generation is handled separately from the solver; the documentation suggests writing grid-generation code or using Pointwise for complicated geometries.fest3d.github.io · 5 Oct 2026
Known issue
The project notes that the halt/stop condition does not work with MPI.fest3d.github.io · 5 Oct 2026
Support contact
The project lists [email protected] as its contact email.fest3d.github.io · 5 Oct 2026
Intended audience
The team describes FEST-3D as an aerodynamic flow solver and provides tutorials for cases including a wedge, smooth bump, lid-driven cavity, flat plates and an airfoil.fest3d.github.io · 5 Oct 2026
