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halt/stop condition does not work on MPI and turbulent simulations cannot run on Windows Subsystem for Linux because of outdated OS and libraries.fest3d.github.io · 4 Oct 2026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
