ParaView Interface



To Hands on Session 1

Break-out room (hands-on session 1) will start in:

Hands On Session 1:
ParaView Basics

Launch Paraview Bookmark

ParaView Window


Simulation of the flow of air around a heated and spinning disk

Open Data


Load All Variables

  • Click the checkbox to enable all variables in the properties panel and then click apply

Add Stream Tracer

  • While having the data selected in the pipeline browser, add a stream tracer filter to the data

Add Stream Tracer cont.

  • Set the seed type to "Point Source" and click apply to make the filter active

How to Search for Filters

  • Click the filters menu in the top bar and select search

Add Tube Filter

  • type all or part of "tube" to find the tube filter the press enter to add it

Activate Tube Filter

  • Once again, you must click apply in the properties panel for the filter to activate
  • You can also click the eye icon to apply

Add Glyph Filter

  • Select the stream tracer object in the pipeline browser
  • Add a Glyph filter from then filters bar

Configure Glyph Filter Properties

  • Glyph type: Cone     Orientation: V
  • Press the refresh scale factor button to automatically adjust scale
  • You may need to manually adjust the scale and click apply to get good looking arrows
  • Masking glyph mode: All points

Configure Glyph Colouring

  • Scroll down to colouring and set the variable to use for colour to "temp"


  • The final visualisation should look like this

Optional Experimentation

  • Try experimenting with different representations for different data points



To Hands on Session 2

Break-out room (hands-on session 2) will start in:

Hands on Session 2:
Paraview Client-Server Mode

Client-Server Mode

  • To visualise large datasets, ParaView comes with the ability to run ParaView across multiple nodes using the distributed-memory paradigm
  • We recommend to run the client on one node - make use of the graphics card on the corresponding node to visualise quickly at the front-end
  • The ParaView servers run on other compute node(s) - The data communication is very fast, as the nodes are connected by an Infiniband cable (100Gb/s signaling rate)

Client-Server Mode

Launch Paraview Bookmark

Open the Server Configuration Window

  • The server configuration for pawsey systems should already be loaded

Configure the Connection

  • Check the training box if you are doing this in a live training session

Enter your Password

  • The password prompt may appear in the console window you used to launch paraview

Wait for the Job to be accepted

  • Be patient as this may take a while if you do not have a reservation

Confirm the Connection is Active

  • If the pipeline browser shows the server name, then remote rendering is active

Optional Activities

Check the status of your Job

Open a terminal (MobaXterm if using Windows) on your laptop


							squeue -u $USER

Showing What Each Server Process is Rendering

For Efficient Parallel Rendering

Open "Settings" dialog box (Edit -> Settings)

For Efficient Parallel Rendering Cont.

“Render View” tab => “Remote/Parallel Rendering Options” => Set “Remote Render threshold” to 0 (Mbytes)

Hands on Session 2:
Large Data and Rendering Movies


  • Dataset – Dam break
  • Column of water behind a membrane
  • At t = 0s, membrane is removed, then; ➡️ column of water collapses
    ➡️ water impacts an obstacle
    ➡️ creates a complicated flow structure
  • 100 total timesteps

Open Data


Activate Data in Render Window

  • Click on the data in the pipeline broswer
  • Click apply in the properties panel

Activate Data in Render Window cont.

  • The data now shows in the render window

Colourise Data

  • Set the colouring to be based on alpha.water in the properties panel

Generate Movie

  • Click on the file menu and then save animation

Generate Movie Cont.

  • Go to your user folder in /scratch where you have write permission
  • Enter a file name and select type ".avi"

Generate Movie Cont.

  • Select the advanced options cog in the top right

Generate Movie Cont.

  • Choose a range of frames to render and click ok
  • All 100 frames will take a long time so choose a range of around 10

Generate Movie Cont.

  • The sofware will play though the anmiation as the frames are rendered and encoded

The final render (all 100 frames)

Copying the Video to Your Local Machine

Hands on Session 2:
Terminating ParaView Servers

Terminating ParaView Servers


Check running jobs for your user

squeue -u $USER

Cancel job by job_id

scancel job_id

Terminating ParaView Servers

Save and close the Paraview client

Terminating ParaView Servers

Close the terminal window opened by the server
