Moreover, the unique solver integrations allows you to define your model once, and then use any and all the CFD solvers interchangeably, which can be invaluable for testing and validation.

CFDTool is suitable for everyone from students and beginners learning basic fluid dynamics and/or heat transfer modeling, to researchers and engineers who can save a lot of time from not having to set up solvers and simulation problems by hand.

State of the Art Simulation Technology!

Define your model only once, and then use the leading CFD solvers interchangeably!

OpenFOAM CFD Solver ⓘ The OpenFOAM solver integration allows OpenFOAM to be used directly from the toolbox GUI. Alternatively, one can also use the toolbox as a CFD-GUI pre/post-processor to automatically create, export and/or import OpenFOAM mesh and case files
SU2 CFD Solver ⓘ The external SU2 Code CFD solver can also be used for fluid flow problems as an alternative to the built-in and OpenFOAM CFD solvers
FEniCS FEA Solver ⓘ FEniCS is a general purpose FEA (Finite Element Analysis) solver which allows FEATool Multiphysics simulation problems to be exported and run independently as Python simulation models and scripts.
Script Modeling ⓘ Every click and step performed in the GUI is logged, can be played back exactly, and has an equivalent 1-to-1 MATLAB function mapping. FEATool Multiphysics can therefore also save and export simulation models as regular MATLAB m-file scripts which is very useful for advanced users to customize, parametrize, and automate their simulations.
User Defined Equations ⓘ In addition to the pre-defined physics modes, FEATool Multiphysics also features full support for implementing completely user defined equations in order to accommodate all types of custom modeling and continuum mechanics simulations

Frequently Asked Questions 

(Click to expand)
What advantages does CFDTool offer compared to other CFD software?

Firstly, CFDTool is one of the easiest to use physics simulation software available, as it has been specifically designed with usability in mind. You can get productive making your own simulations with CFDTool in minutes, without having to work through extensive documentation, courses and tutorials, as often is necessary with other software.

Moreover, CFDTool uniquely offers the capability to interchangeably use multiple physics solvers, such as the built-in multiphysics solver, OpenFOAM, and SU2. You only have to set up and define your model once, and can then seamlessly use all compatible physics solvers to solve the model.

Can your software simulate and model "X"?

The toolboxes and physics solvers are generally designed to be able to solve most systems of coupled partial differential equations (PDE). Some of the more common equations and boundary conditions, such as for heat transfer, fluid flow, linear elasticity etc., have already conveniently been pre-defined (see the list of pre-defined physics modes).

If the problem "X" you wish to model is currently not available among the pre-defined ones, and you know the governing (PDE) equations of your problem, it is generally possible to either modify the existing physics modes or implement your model as a custom equation. How difficult and how much extra work it will require to implement model "X" typically depends on how complex it is and how much it differs from the already available models and equations.

Can you give me an example, model, or tutorial to simulate "X"?

Please understand that, Precise Simulation, as the developer of these toolboxes is fully committed to making it easy for you to use state-of-the-art physics simulation tools. However, being a very small and niche software developer we don't have the resources of bigger firms, and can therefore generally not provide custom examples and tutorials for all types of simulation problems. That said, in general most types of PDE based problems can be simulated with the toolboxes. The currently available learning, example, and modeling resources are the following

If you do not find a model or example similar to what you want to simulate, and want us to create a one for you it would be possible to do as a custom . Alternatively, please feel free to submit a feature request to the user community and discussion forum.
