SimWorks Licence FAQ

SimWorks is a free CFD software and does not have any limitations to the number of cells the user can define. Our vision is to bring CFD to the widest possible audience. In addition to being free, SimWorks is designed to be as user friendly as possible and has a wide collection of tutorials to introduce the user to any functionality. 

We also develop a commercial CFD software called SimWorks Manager that supports multiple-simulations (any number) and can be run in parallel without limits on core count. It also features many more physics models and functionalities. SimWorks Manager is ideal for professional and industrial users. In the most recent version, the functionalities of SimWorks Manager have been brought to the free version,  SimWorks, but with limits on their use. 

We want to encourage the users to try the advanced features and come back to us with some feedback, even if they are not going to actually upgrade to SimWorks Manager users can still register SimWorks for free and get an increased level of functionalities. The upgrade process is very easy and completely free, see the following point.

You do not have to pay to get additional functionalities. We are interested in creating a community and we value feedback and interaction with our users. So you can register your version of SimWorks for free either during the first install or afterwards by clicking on the Lincence entry in the main GUI and then Upgrade… and finally follow the on screen instructions. Registering your version will unlock more functionalities for free. To access unlimited parallel computing and additional SimWorks Manager features, you can start a SimWorks Manager free trial following exactlt the same procedure used to register SimWorks, see also the following point for reference. 

We will not use your details for any purpose other than getting feedback. You can unsubscribe at any time and you would still maintain the additional functionalities. Also no payment details and no committment is required at any stage both to register SimWorks or to get a free 14 days trial of SimWorks Manager.

You can automatically get a free 14-day trial of SimWorks Manager which does not have any limitations and there is no need to provide any payment details. You can start the free trial by either downloading SimWorks Manager directly or afterwards by clicking on the Lincence entry in the main GUI and then Upgrade… and finally follow the on screen instructions

Once the trial period has expired, if you do not wish to extend it, the software will automatically revert back to the free SimWorks version unless you contact us to get a licence extension.

The licence is tailored to every customer and we offer discounts for multiple licence purchases. The cost of a single licence of SimWorks Manager is roughly 85% less than most of the commercial CFD packages available on the market today. We are able to to offer such competitive prices because our software is developed on top of open-source packages, like OpenFOAM. We want to engage with the widest possible audience and we thought that lowering the price barrier would have been an effective way of getting more people into using CFD. 

Also we offer substantial discounted packages for multiple licences purchases which often include additional services. Simply contact us specifying your needs and we will come back to you with a tailored quote. This will obviously be free and with no obligations.

We are very interested in liaising with students and universities and we are therefore happy to offer academic licences of SimWorks Manager for free. The only limitation is that SimWorks must be used for research activities only, and not for commercial purposes. The licenses will be time limited (generally for the duration of the project) but can be further extended. This is because we are very interested in maintaining an open conversation with academic users.

At the same time we would be very grateful if SimWorks and the IdealSimulations website were cited as one of the tool used in an academic work.

Absolutely, we offer bespoke packages and quotes to companies looking to purchase multiple licences. We can change anything in the software from the GUI to implementing additional functionalities, this allows to create a truly bespoke product with only the features a company really needs

Replacing a commercial software with a bespoke version of SimWorks Manager would then both lead to a reduced cost and crucially to a product better tailored to the user needs without additional functionalities not required. On the other hand implementing a bespoke version of SimWorks Manager as the first CFD software a company uses would lead also to substantial savings in training since the product would be tailored to the current engineers wishes rather than require the engineers to adapt to a new software package.

SimWorks Technical FAQ

SimWorks Manager is designed around the concept of CFD design process, allowing multiple simulations to be defined, managed and run at the same time in the Simulation Manager environment (hence the name SimWorks Manager). It supports the quick duplication of simulations, by re-using the existing simulation parameters applied to new geometries, and also allows to quickly define portions of the geometry as independent part groups to define different boundary conditions or different mesh groups to define different mesh settings

Those features make SimWorks Manager extremely fast for defining new CFD simulations and to carry out design iterations on an existing solution. 

Moreover SimWorks Manager is extremely cost effective making it a viable solution also for small and medium enterprises.

SimWorks does not cover the full spectrum of OpenFOAM models and functionalities, but we aim to bring into SimWorks as many new features as possible. The commercial users will have direct access to any new feature and model introduced in SimWorks Manager as included in the base licence. Over time, some of the advanced features will also be ported to the free version SimWorks. 

If you still cannot wait for us to implement new models, you can modify the OpenFOAM dictionaries yourself after they have been generated. SimWorks maintains full compatibility with OpenFOAM without touching neither the source code nor the dictionary structure. You can find a lot of material on how to setup an OpenFOAM simulations and define the required dictionaries on the OpenFOAM website.

On the other end, if you are a commercial user and would like to a have a bespoke feature added to SimWorks Manager, do not hesitate to contact us. We would be happy to discuss with you about additional features or for tuning the software for your specific needs, as an additional service.

SimWorks Support FAQ

The installation procedure is completely automatic, so you simply need to follow the installation guide on our website. Please note that the installation can take some time, as the installer needs to download and install the SimWorks executable and a full Linux distribution. Please be patient and follow the instructions during the initial setup. If you do have any issues, please contact us and we will be happy to assist!

Like other small software vendors, we do suffer from false positives from some antivirus software. Our code is signed by a third party body (Global Sign) and it is absolutely secure. Please visit our SimWorks security section for more info.

You can either add SimWorks as an exception to your antivirus software or you can follow the manual installation guide, which show you how to reproduce each step of the installation procedure manually, i.e., download and unzip the required files from our website and activate the Window Subsystem for Linux (WSL) on your machine.

SimWorks fully supports the most common CAD exchange formats like .igs and .step. There are multiple ways of importing new geometries, please find all the info you need in our CAD import guide.

Sometimes the geometrical engine behind SimWorks is not able to recognise individual faces inside an imported igs or step file. Most of the time there is nothing wrong with the geometry and we advise to separate the different parts of the geometry in CAD into independent igs files and load these up as multiple files. To do so, when clicking on the import button, select them with ctrl + click and then splitting the parts into independent part/mesh groups. Alternatively, you can import individual files one at a time and in this case independent part groups for each file will automatically be created. More info are in our CAD import guide.

IdealSimulations only offers support for bug fixes with highest priority given to the SimWorks Manager users, so if you find a bug do not hesitate to report it. You can also contact us to agree the terms of the engineering support required to help you define your own simulations.

SimWorks Learning FAQ

Whether you are a CFD professional or someone with little experience, we would encourage you to follow our tutorials. They are very practical and easy to follow, some of them are also available on our Youtube channel. This will show you progressively all the main functionalities of SimWorks. We recommend starting with the SimWorks introduction and then the tutorials are arranged into categories according their difficulty, from Base to Intermediate to Advanced. Please complete all tutorials in one category before moving to the following one.

Surely not! SimWorks offers a very user friendly way of defining a new CFD simulation. You just need a basic CFD knowledge and you don’t need to have used OpenFOAM previously.

SimWorks also keeps the OpenFOAM dictionaries open and accessible, this way users can progressively get more hands on with the code in case they want to make bespoke modifications to the simulations.

We can provide bespoke training courses for companies. Please contact us to get all the details of the different training packages available.
