CFDTool, is based on the FEATool Multiphysics software and simulation platform, and features a simplified user interface that has been specifically designed and developed to make computational fluid dynamics (CFD) and heat transfer simulations both easy and fun!
The toolbox is fully integrated with MATLAB, everything you need to set up, perform, and analyze CFD simulations, including CAD geometry modeling, automatic mesh generation, postprocessing and visualization, as well as built-in support for the OpenFOAM and SU2 CFD solvers.
The intuitive GUI allows you to start modeling right away without spending time learning a complex solver or programming syntax. Non-linear expressions and coefficients can be defined and entered just as written on paper.
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 GUI is one of the leading solvers for computational fluid dynamics (CFD) simulation, and used in industry by for example VW, BMW, Ford Motor Company, Airbus, Siemens, and General Electric
The Stanford University SU2 Code is a popular academic research CFD solver applicable to a wide range of specialized fluid dynamics problems such as compressible flows and aerodynamic shape optimization
CFDTool features native integration with MATLAB and supports calling user defined m-file scripts, solvers, and custom functions for example for material, boundary, and postprocessing coefficients

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 you give some references to users of your software?
Please see the partial list of public references to the software. Moreover, some user submitted showcase models are also presented in the model gallery.
Can CFDTool 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, in FEATool Multiphysics 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.How does the online purchasing process work?
Online credit card payments are processed securely using Stripe and charged in your local currency or US Dollars (USD). After an online payment has been successfully processed your web-browser will automatically be forwarded to a new web page where you will find an activation token/code and instructions for activating all software features (please do not press the back button, change, or close the page during the purchasing process). After the purchase you will also receive a receipt to your email address.
Can we purchase by quotation, purchase order, and invoice?
Yes, academic and commercial licenses are also available to purchase via invoice in major currencies (USD, EUR, GBP, JPY, CNY, and HKD). If you wish to initiate a purchase, please with the following information
- Name and contact details
- Purchasing company/institute and address
- Toolbox (FEATool/CFDTool), license type
- Academic or Commercial use
- 1-Year
- Perpetual
- With or without technical support
Note that personal licenses are not currently available to purchase via invoice (only through online direct purchasing, a sample online purchase receipt can be seen here).
What is the return and refund policy?
We offer free downloads and trials with limited funtionality for as long as you like. Full trial versions can also be requested if you wish to try all features for 30-days. Please do try and make sure the software works for your intended usecase before purchase. If you still are not statisfied with the software 15-days after purchase we evaluate and process refunds on a case by case basis.
Products purchased from sources other than Precise Simulation, such as a reseller or distributor, must be returned to the source from which they were purchased and are subject to that source’s return policies.
What is a perpetual license and how does it work?
In contrast to a time limited license which will stop working after a designated time (1 year), a perpetual license will not expire and allow you to use the software perpetually (forever).
Software updates are included with all perpetual licenses for the first year. However, in order to fund continuing development, an optional software maintenance fee is charged after the first year to continue receiving updates (currently 20% of the perpetual license cost per additional year).
Note that this is entirely optional, and you can always continue to use the last valid version that your license was eligible for.
What is a class kit/room license (CKL) and how does it work?
A class kit or class room license (CKL) is a academic discounted license type valid for undergraduate class room use. The class kit licenses are only valid to be installed on computer systems in a institute lab for undergraduate students. The CKL license is not allowed for use on personal systems with exception of the instructor/teacher.
Class kit licenses are limited to 1-year duration (perpetual CKL licenses are not available at this time), and are available for 15 or 30 concurrent seats/users + 1 teacher/researcher.
For how long do I get updates and/or technical support?
- Time limited licenses include all updates for the duration of the license (1 year).
- Perpetual (non-expiring) licenses include updates for 1 year (and technical support if purchased), after which the update and/or support maintenance contact can optionally be extended for 20% of the current license price per additional year. Please
What technical support options do you offer?
Limited free support is available through the public community and discussion forum forum.featool.com. The forum is primarily meant for toolbox users to be able help each other, so please do join and help other users.
Alternatively, dedicated developer support, with resolution, advice and software fixes within 24h whenever possible (depending on the severity and nature of the issue) is available as an additional option with all licenses. This includes questions on usage, technical issues and bugs, and modeling questions (with available/existing functionality).
Questions, issues, custom features or models that require extensive implementation work or research are handled as a , where we can dedicate ourselves to really make your modeling and simulations a win for you.
