FAQ

Answer

QLabs Virtual Experiments are digital twins of Quanser hardware that you can run the same as you would physical hardware, using out-of-the-box or custom models in MATLAB®/Simulink®. QLabs Virtual Experiments only run in the Quanser Interactive Labs application for Windows 10.

QLabs Controls is a stand-alone lab solution for controls engineering students. It includes a self-contained experiment console and requires no additional software. QLabs Controls is available in the Quanser Interactive Labs application for Windows 10, macOS, iOS, and Android.

Answer

The curriculum resources for each QLabs Virtual Experiment can be found in the Quanser Interactive Labs application on Windows 10. Open the QLabs Virtual Experiment that you would like to work with, then open its Workspace. At the top right of the screen is a book icon that will download the curriculum resources.

If you’re an instructor, the Instructor Version of the curriculum resources were emailed to you in your initial email.

Answer

The graphics quality settings of the Windows version of the application can be adjusted to improve performance. Log into the Quanser Interactive Labs application and click on the Settings icon to adjust the framerate limit and shadow quality.

Answer

Click on the Sessions tab at the top of the screen, then click on your lab session. Scroll to Member List and click Add Users. Upload or copy/paste your class list as line-separated values, and click Add Users again. Users in the Member List will have access to your virtual hardware for the remainder of your lab session.

Answer

Yes, Session Assistants can add students to your lab on your behalf. Click on the Sessions tab on the top of the screen, then click on your lab session. Scroll to Member List and add the user you would like to make a Session Assistant. Once added, select the user’s email using the checkbox and click on Update Session Role. Select Assistant and click Save.

Answer

You can add Session Assistants if you would like to give someone else permission to add students to your lab on your behalf.

If you would like to completely transfer the session to another user (i.e. someone is taking over your lab), please contact digital@quanser.com.

Answer

QLabs Virtual Experiments are only available in the Quanser Interactive Labs application for Windows 10.

A few options are available for macOS users wishing to run Windows applications, including Boot Camp and Parallels.

Answer

Quanser Interactive Labs has not been thoroughly testing on virtual machines, although it may be possible. From what we’ve seen the Quanser Interactive Labs application typically doesn’t perform well on virtual machines in terms of real-time and GPU performance.

Answer

A standard QLabs license is designed for single and multi-class use. If you require departmental or faculty access, please contact a member of our team.

Answer

Yes! Like the Quanser physical hardware that they represent, QLabs Virtual Experiments are designed with open architecture, so users can design their own controllers.

Answer

All Quanser curriculum resources are written using an open format, so they can be edited freely. For older curriculum documents not created using open format, contact us for an editable version (Word, RTF).

Answer

At this time it is not possible to run physical and virtual hardware using the same computer.

Answer

Since QLabs Virtual Experiments are digital twins of physical Quanser hardware, the curriculum resources are essentially the same. The key difference is the configuration of the MATLAB®/Simulink® model to target the virtual version of each product. The documentation is written for the physical versions.

Answer

These errors indicate that the installer did not detect MATLAB, and therefore did not install QUARC properly. There are a few reasons you may be seeing this issue.

1. We see this issue when MATLAB®/Simulink® is installed after the Quanser Interactive Labs application. Verify that MATLAB®/Simulink® is installed, then uninstall and reinstall the Quanser Interactive Labs application.

2. Something may have prevented the installer from associating the Quanser Interactive Labs application with MATLAB®/Simulink®. This can be fixed from inside the MATLAB® application. Open MATLAB® and navigate to the QUARC folder at
C:/Program Files/Quanser/QUARC/quarc
and run the quarc_setup.m script. Close and relaunch MATLAB®.

3. You may have a non-supported configuration of MATLAB®/Simulink®. The most common issue would be a version that is older than 2019a. In that case, please update your version of MATLAB.

4. Please try running the Quanser Interactive Labs installer as "Administrator" to ensure that it has permission to launch MATLAB. Alternatively, try running the installer with the MATLAB application open.

Answer

This is an issue with Microsoft DirectX, which is required to run the Quanser Interactive Labs application on Windows 10.

Try restarting your computer. If that doesn’t work, download and re-install the latest version of Microsoft DirectX.

Answer

We typically see this error when a graphics card does not meet our minimum specifications. It is an issue with Microsoft DirectX, which is required to run the Quanser Interactive Labs application on Windows 10. Ensure that you have the complete feature set of Microsoft DirectX 11 or later installed on your machine.

If you are unable to use Microsoft DirectX 11 you can still run the Quanser Interactive Labs application using Microsoft DirectX 12 but will see a marked decrease in performance. Navigate to the following folder:
C:\Program Files\Quanser\Quanser Interactive Labs\QLabs\Binaries\Win64\
and from the command line, run the executable that’s there (QLabs-Win64-Shipping.exe) with the following flag –dx12

Answer

This is expected behaviour, as we do not currently sign the Quanser Interactive Labs application for macOS for distribution on the App Store. To solve the issue:
1. Move the .app file to the Applications directory (admin authentication required).
2. Go to System Preferences > Security & Privacy and click the QLabs > Open Anyway button. It will ask if you’re sure, and click Open again (authentication required).
