Installation & licensing

I am trying to install simFlow on Linux, but it does not recognize the executable file, which I downloaded. Why?

During simFlow installation on Linux, a few additional actions may be required from the user. Most often you have to make the downloaded file executable. Check for details here.

What are the limitations of the evaluation mode compared to the commercial mode?

Basically the main limitations are 100’000 mesh nodes limit, unavailable meshing in parallel and parallel computing limited up to 2 cores. Check for details in the table here.

Can I use simFlow in the evaluation mode during classes at the university for teaching?

Yes, of course. Feel free to use it in commercial and educational cases.

Why does the software require an internet connection?

simFlow connects to the internet in order to check the validity of your license. If you do not have an internet connection, simFlow will start in the evaluation mode.

How do I know that I am running simFlow in the commercial mode?

When you run simFlow and there is no remark ‘simFlow evaluation’ below the simFlow logo, it means that the license file has been detected by simFlow, and you are running simFlow in the commercial mode. It also means that all the limitations of the evaluation mode do not apply to you.

What will happen after my simFlow license expires?

After the licensing period expires you can renew your license or use simFlow in the evaluation mode.

Do you offer both short-term and perpetual licenses?

Yes, we do offer a wide variety of licensing plans, starting with a 3-month licensing period and ending with perpetual licenses. Contact us for details using the contact form.

When I attempt to download simFlow I get the error message ‘Signature corrupt or invalid’. Why?

Most likely this problem is caused by a bug in Microsoft’s web browser, which incorrectly interpret a valid certificate as corrupt or invalid. In order to avoid this problem, please use a different web browser when downloading simFlow installation package.

Which files should I include when sending a sample case?

If you have a problem with your simulation, please delete all the folders containing the result files from the case directory, which are named according to time-step or iteration number. Then, compress the case directory and upload it to a cloud or hosting provider, for example, using Dropbox or Google Drive, and provide us with a link to the archive. Please do not send large files to us as attachments to your emails, as we may not receive them due to technical limitations. You can use the contact form on simFlow home page.
