Virtual Lab

The Engineering Virtual Lab is a way for you to gain access to most of the Engineering software from a remote location. By using this tool you will be able to do homework or projects from your home or dorm room.

Connect to Virtual Lab

Supported Web Browsers

We recommend using Chrome, Firefox, Opera, or Internet Explorer. These browsers will recognize the Citrix client and load the published application correctly.

Other browsers, such as Safari, may work, but are not ideal. These browsers start the published application using the Java plugin. One of the problems with the Java plugin is that it does not correctly utilize Ctirix load balancing or recognize which computers are currently in the "farm" (i.e., the pool of computers available for this resource). At times the Java plugin connects to computers in the farm and then at other times it tries to connect to servers that are not in the farm.

Policies

Please read this section carefully! You may be denied access to the Virtual Lab if you fail to abide by these policies.

  1. This resource is for academic teaching purposes only. Do not use this resource for any non-academic or commercial purposes.
  2. You may not use this resource outside of the United States.
  3. Due to the scarcity of session licenses, any Virtual Lab session that is idle for over 24 hours will be automatically logged off so that others can use this resource.
  4. Engineering students have access to the Virtual Lab. By default, faculty and staff do not. Faculty and staff may pay an annual fee to access the Virtual Lab for course-related purposes; please contact ENS for details.
  5. Please do not consider the Virtual Lab a purely distance education tool, or a substitute for the physical computer labs. The Virtual Lab is meant to be used as a convenient supplement to the physical computer labs. It is a student-funded project and thus only students have access.
  6. Specifically for ANSYS software products, you may not use the software installed on the Virtual Lab outside of a 50-mile radius of the Fort Collins CSU campus.

Many of the restrictions above are based upon licensing restrictions from the software companies, which we must agree to in order to use their software.

Connecting from a Desktop or Notebook Computer

  1. Uninstall any versions of the Citrix Receiver, or Citrix Online Plug-In, that you currently have installed.
  2. Install the latest Citrix Receiver for your operating system.
    Note: You do not need to select Add Account at the end of the install. Just click Finish.
    Firefox users: See the Troubleshooting note below for further steps.
  3. Open the Virtual Lab access page.
  4. Log in with your Engineering user name and password.
  5. If the Virtual Lab page prompts you to install the Citrix client, select Already installed.
  6. Optional: If you want to modify the screen size of the Virtual Lab application (recommended), see the Tips note below for further steps.
  7. Click on the Virtual Lab icon to log into the Virtual Lab.
  8. The Citrix Receiver will ask you for permission to access your local files. If you answer Yes, then you will be able to transfer files between your local computer and the Virtual Lab. This is secure and you will be the only person that is able to access your local computer's files. We recommend that you answer Yes, and check "Do not ask me again for this site".
  9. Congratulations.  You are now in the Virtual Lab. Note that you may Disconnect from your session, or Log Off (see below for the differences).

Tips & Troubleshooting

Make sure you have the latest Citrix Receiver installed.
We recommend you uninstall existing versions of the Citrix Receiver that are on your computer, then install the latest Citrix Receiver from the Citrix web site.
I am using Firefox version 30 or above, and the Virtual Lab application will not launch.
Follow these steps:
  1. Uninstall any existing versions of the Citrix Receiver.
  2. Install the latest Citrix Receiver from the Citrix web site.
  3. Open Firefox, and type the following in the address bar: about:addons
  4. Find the entry for "Citrix ICA Client". On the right, change the drop down setting from "Ask to Activate" to "Always Activate".
  5. Find the entry for "Citrix URL-Redirection Helper Plugin". On the right, change the drop down setting from "Ask to Activate" to "Always Activate".
You receive the following error message: "You already have an instance of this application open and are not allowed to run more than one instance. Please contact your System Administrator."
Your old session may not have disconnected properly. You can perform the following procedure to fix it yourself:
  1. Log in to the Virtual Lab web interface.
  2. Select the Problem Connecting? link on the lower right-hand side of the page.
  3. Use the Disconnect link on the grey toolbar on the upper right-hand side of the page.
  4. This will disconnect your session on the server and log you out of the web interface.
  5. Log back in to the web interface. At this point you can restart your session.
  6. If this method does not work, please contact ENS.
The Virtual Lab window is too small; OR
I want to modify the screen size of the Virtual Lab application.
Follow this procedure to resize the window:
  1. Log in to the Virtual Lab access page, but do not open the Virtual Lab application yet.
  2. Select the Preferences tab at the top of the page, then select the Session Settings option.
  3. Change 'Window size' to your desired size. We recommend using Percentage of screen and set that value to 95%.
  4. Click Save, then click on the Virtual Lab application as usual.
I can't find Xming (or similar X-forwarding tool) to log in to the Linux servers.
That's because there is a better way to connect to the Linux servers than the Virtual Lab! Use Remote Desktop to connect to the Linux servers directly.
