Setting Up a Desktops Session

Running Desktops

The following instructions detail how to use the Desktops feature to perform remote visualization on the Rescale platform using the "Desktops" feature. Please contact us if you're having trouble.

In order to access the Desktops remote visualization feature, log into your Rescale account (Rescale Platform) and submit the simulation that you would like to visualize in the cloud. If you don't have a Rescale account, you can create an account at no charge here: Rescale Signup. You can also perform remote visualization on a job you've previously executed. To run and visualize the job that is used in this example, import this simulation. Since this simulation has already been run through Rescale's Tutorials Account, you do not need to run it again in your own account.

To proceed with running a Desktops session, click on the Desktops tab and select + New Custom Desktop.

New Desktop

You can give your session a unique title to locate it easily later. Next, you can select from Windows or Linux, CPU or GPU instances. For this tutorial, we'll be running on Windows CPU. Also, please add the Software (ParaView) and Job (OpenFOAM ParaView Server) to the desktop through the interface (shown below).

Once you've made your selection, you can click "Launch" and it will start the session. This will typically take a few minutes.

Custom Desktop

In general, these are the required ports for visualization:

RDP: Port 3389
VNC: Port 5900/5901

Once the server has started, you need to click the Connect button which will show a popup (as seen below).

Windows Desktops

The easiest way to view your desktop is through In-browser Desktops, which can be accessed simply by the click of the Connect using In-Browser Desktop button, as shown below. You are now be able to use the remote desktop straight off your browser.


If you would prefer to use a client to connect with the desktop instead, please follow these instructions:

You need to first click on Generate New Password, followed by Download RDP file.

Connect Desktop

To visualize Rescale Windows remote desktops from a non-Windows machine, you will need to install Microsoft Remote Desktop for Mac (download) or Remmina for linux (download).

Once the RDP file is downloaded, double click to open. For GPU-enabled instances, it is recommened that you use NICE DCV Endstation for visualization instead (download). You will be prompted to type in the password (case-sensitive) when launching the visualization through NICE DCV.

Once you are at the Windows user Sign-in page, you will also need to enter your unique password (case-sensitive).

Windows Login

You should now be viewing your remote desktop. The shortcut to the attached Software can be found on your desktop.

Windows Desktop

Linux Desktops

If you are looking to launch a basic Linux instance, you will need to set up an ssh tunnel first. Download the relevent script (Windows or Linux), and follow the instructions on the page.

Windows Desktop

You need to first click on Generate New Password, followed by Download VNC file.

For utilizing GPU-enabled Linux remote desktops, it is recommened that you use NICE DCV Endstation for visualization (download). You will need to enter your unique password (case-sensitive) in DCV Endstation.

You should now be viewing your remote desktop. please use the terminal to navigate to and launch the executable under the /program/ directory.

Example Visualization of an OpenFOAM job using Paraview


To open the job, go to the mapped drive. On Windows, it is common to map to the Z: drive, but the attached job could be in the X: or Y: drives as well depending on your setup.


Select run1.


At the bottom of the pop up window, go to Files of Type and select All Files from the bottom of the list.


Select the file you want to visualize. In this case, it is file f1.OpenFOAM.


In the next window, select to open the data with OpenFOAM.


Now that you've added the job to ParaView, you can set the requirements to view the model. On the left side of the screen, check the box labeled F2007 to open the job used in the simulation.


Click Apply in the left, middle side of the window to visually load the model.


To remove the boundary conditions, type Ctrl and the Space-bar simultaneously to bring up the pop up window. Type Extract Block and then hit the Enter button to filter out the boundary conditions.


In the Pipeline Browser on the top left side of the user interface, left click on Extract Block. In the properties section below, click on Patches and then select the Apply button just above.


Finally, click on the F1.OpenFOAM file in the Pipeline Browser on the top left side to visualize your model.
