MATLAB CFD Simulation Toolbox

Performing complex flow simulations in MATLAB has never been as easy and straightforward as with FEATool Multiphysics. The built-in and dedicated GUI makes it quick and easy to set up and solve complex computational fluid dynamics (CFD) simulation models directly in MATLAB.

FEATool Multiphysics fully supports most types of steady and instationary, laminar and turbulent, porous and non-Newtonian types of fluid mechanics and flow engineering problems. Moreover, with the multiphysics capabilities, the pressure and flow fields can directly be coupled with different physical phenomena such as heat and mass transport, allowing for complex interactive CFD simulations as for example in multiphase and reactive flows. Also, with higher order built-in simulation schemes, sensitive quantities such as aerodynamic lift and drag forces can be evaluated with high accuracy.

CFD Solvers

FEATool Multiphysics includes built-in flow equations and solvers for viscous incompressible, inviscid compressible, porous media flows, and fluid-structure interaction. Moreover, FEATool also comes with convenient one-click GUI interfaces to the dedicated external CFD solvers OpenFOAM, SU2, and FEniCS.

This allows users to set up and define large scale high-performance CFD simulations directly from the MATLAB GUI interface. The OpenFOAM, SU2 and FEniCS solvers can then be used to perform parallel CFD simulations, as for example illustrated with the flow over an aircraft wing FEniCS HPC simulation simulation.

Multiphysics for Fluid Dynamics

The easy to use pre-defined flow equations and/or physics modes in FEATool Multiphysics makes it easy to set up coupled and fully interacting fluid flow problems in any space dimension.

FEATool Multiphysics can also parse general nonlinear expressions, including coupled dependent variables and derivatives. This allows users change and modify equations and to define complex equation coefficients, without any programming at all, by simply typing in the expression just as written on paper. This can for example be used to quickly define non-Newtonian and non-isothermal fluids by modifying the density and viscosity expressions to include a temperature dependence.

Computational Fluid Dynamics Tutorials

FEATool Multiphysics makes it especially easy and convenient to learn CFD simulation with several built in and automated step-by-step flow modeling tutorials available directly from the GUI by selecting Model Examples and Tutorials... > Fluid Dynamics > from the File menu.


Precise Simulation also develops a simplified toolbox, CFDTool, for CFD simulations with coupled heat transfer. CFDTool features a simplified GUI interface without PDE equations making it easier to get started with fluid dynamics simulations. Visit the CFDTool website for more information.
