Frequently asked questions

Does Flowgy run on a Linux platform?

Yes. Flowgy runs natively on Linux. Flowgy has been developed on the Linux operating system, and more specifically on the Debian-based Ubuntu distribution.

Does Flowgy run on a Windows or MAC?

Yes, Flowgy can be used on these two operating systems using some virtualization software, such as VMware or VirtualBox. In fact, it is a solution adopted by a large majority of our customers and partners. We have virtual machines with a pre-installed Linux operating system ready to install Flowgy and use it on Windows and MAC. Using this solution means a loss of approximately 40% in Flowgy's performance. Considering the power and performance of the mid/high end computers available today, this is not significant and Flowgy will work perfectly.

In the case of Windows 10, it is also possible to use Flowgy natively by activating WSL and installing one of the available distributions (in our case the Ubuntu distribution). Using a Windows X server (like Xming, which is free), Flowgy's graphical environment will work perfectly and on the Windows 10 operating system like any other application.

What are the recommended operating system requirements for Flowgy?

The recommended operating system for using Flowgy is Linux (Ubuntu distribution 18.05). Flowgy has been fully developed on this operating system.

Because of the large number of distributions that Linux has we can only offer technical support for the Ubuntu distribution 18.05 and above.

What are the recommended computer hardware requirements for Flowgy?

–   Intel or AMD processor at 3GHz or higher (an Intel multi-core processor is recommended).

–   16 GBof RAM (> recommended).

–   100 MB of available hard-disk space for installation; additional free space is required for Flowgy generated files and CT scans. An SSD disk is highly recommended.

–   Screen resolution 1920x1080.

–   A good graphics card (NVIDIA recommended) with an accelerated driver installed.

–   A permanent Internet connection. Some ports should be open.

–   Anydesk software (https://anydesk.com) installed.

Can I use this software for teaching?

Yes, Flowgy can be used for educational purposes. Some universities, such as the Universidad Politécnica de Cartagena in Spain, use Flowgy as an aid to CFD calculation in anatomical structures.

How can I download the latest version of my licensed Flowgy software?

To work with the latest version of Flowgy just open the program and go to help> Check for updates > Update Flowgy

How do I install my Flowgy software?

When you purchase a license, you will receive an email with a link to one of our encrypted servers from which you can download the program.

Once you have downloaded the program, you only have to open the Flowgy file and follow the instructions below:

How to install Flowgy

How can I get a username and password for my Flowgy?

Both the Flowgy username and password are provided by the Flowgy development team when the customer purchases a license.

Can I change my username and password?

The user does not have the option of changing either the username or the password himself.

The user name is automatically assigned once the license has been purchased, and is required for the installation of Flowgy, along with the password.

The password can be changed, if the User wishes, by the Flowgy development team. To do so, you must contact us at technical.support@flowgy.com and request a new password, which you can choose yourself.

What is a Study and how does it works?

A Study is a kind of container where the user saves and groups all the information (CT Scans, Virtual Surgeries, CFD Solutions, Reports...) that he considers common for his management. Through studies the user can keep his work organized and available at any time.

What is an Image Segmentation?

It is the process by which a digital image is partitioned into multiple segments (pixels), and whose objective is to simplify the representation of the image for a more efficient analysis.

What does DICOM and what is it?

DICOM (Digital Imaging and Communication On Medicine) is a standard for transmitting medical images and data between hardware for medical purposes. The most common applications of this standard are the display, storage, printing and transmission of images. The protocol includes the definition of a file format, a network communication protocol based on TCP/IP.

What does NRRD and what is it?

NRRD is a file format designed to support scientific visualization and image processing involving N-dimensional raster data. NRRD stands for "nearly raw raster data".

What does FLOWGY stand for?

flowgy is the native format of the software. All files saved from the software itself, and as long as no other format (such as DICOM or NRRD) is explicitly specified, will be saved in flowgy format.

The flowgy format can only be opened from the Flowgy software itself.

Can I import a Segmentation from another software?

Yes, Flowgy supports the NRRD format as a format that contains images that have been segmented with other programs such as ITK-SNAP, 3D Slicer, Seg3D, Materialise Mimics etc...

Can I improve the velocity of the CFD Solver?

Yes, Flowgy has a Plugin/Add-On that allows to solve the flow of the fluid using more than one CPU, that is, using software parallelization techniques that considerably accelerate the computation times of the CFD.

How do I get Flowgy Envision?

Flowgy Envision is distributed for free with the Flowgy license. However, reporting in Flowgy Envision format is not allowed in the demo or basic version. It can only be used for the display of reports generated by the Flowgy development team itself.

How many reports can I create?

You can create as many reports as you want, no limits.

Can I protect a report with a password?

Yes, the .pdf reports generated by Flowgy can be password protected and encrypted.

Does Flowgy collect any kind of personalized data of the patients?

No. At no time does Flowgy access personal or confidential information contained in the CT Scans or similar and that Flowgy will use throughout the computing process.

How can I anonymize the patient data in a DICOM file?

Flowgy has tools that allow the user to generate a DICOM or similar that will be a copy of the CT Scan or similar of the patient, but totally anonymized, that is, in which all personal and confidential information of the patient and other data will have been removed. This DICOM or similar can then be used by Flowgy.

How can I collaborate with Flowgy?

We want to make our vision a reality - to create a medical world in which technological innovations are accessible to all and significantly improve people's quality of life - with partners who also share our dreams.

How long does it take to learn Flowgy?

Flowgy is designed to provide the best possible user experience, reducing complex computational tasks to a few clicks.

To speed up the learning process, Flowgy makes available for free the Flowgy Academy, a documentation in the form of video-tutorials that covers everything you need to know about Flowgy, from how to navigate the interface to how to get the most out of the different features of the software.

How long would it take me to get the results of the airflow in my patient's nostrils from their CT scan?

The time that a user has to spend from the moment Flowgy reads the CT scan until the user sees the final results of the simulation is approximately 15 minutes. Furthermore, additional time will be needed for Flowgy to perform the air flow calculations using Computational Fluid Mechanics techniques, and this time will depend on the capacity and power of the computer used. For a computer with the performance recommended by Flowgy, this time will be about 2 hours.
