More specifically, here are helpful pages for AVS/Express users:

Training and tutorials

And here are materials from training and tutorials I delivered:

The AVS/Express Workshop

Currently the most important training event to which I contribute is the AVS Workshop held at the ETH Zürich. The current one has been held on May 23rd, 2013. Here are the slides of the “Introduction to AVS/Express” course from this edition.

Instead here you can find material from the previous editions:

Here are few AVS/Express resources that will be mentioned in the presentation:

Some AVS/Express projects

on which I worked in the past

[STM4 appearance]

STM4 molecular visualization toolkit.


  • Library of components plus two new data types
  • Benefits from module architecture
  • Decoupling of AVS/Express interface from code through an interface library
[MOD3D screenshot]

MOD3D – Tool for 3D reconstruction of undersea biological structures starting from a movie. This work has been done for ENEA CRAM (Marine Environment Research Center) that has published a paper on it.


  • Almost all was custom code
  • GUI capabilities were critical (Data Viewer not used)
  • Few visualization technique used
  • Added modules for zooming, marking and navigation
[Ferrari F1 car]

Distributed CFD data access for FERRARI Racing team aerodynamic simulations.


  • Standard visualization techniques plus some data cut/optimization modules added
  • Fluent reader added to AVS/Express
  • Big data sets
  • Performance were critical
  • The prototype benefited by quick prototyping capabilities offered by AVS/Express (unfortunately the project stopped at the prototype phase…)
[Air flow inside a car]

ELASIS immersive CFD visualization. ELASIS is part of the Fiat Group and supports the design of car interiors and apparatus.

Here is one of the view of the prototype. It displays the immersive menu and one of the visualizations. It has been developed with AVS/Express Multi Pipe Edition.


  • Standard CFD techniques
  • Input already in AVS UCD format
  • Use immersive Multi Pipe Edition (with wand and head tracker)
  • 3D widgets usable also from standard screen
[Fluent Inc.]

Created the Fluent Native Format reader for AVS/Express.

This module, together with research on huge data access and visualization, formed the basis for the FERRARI Racing team prototype.



[Pelton turbine simulation results]

Experimental and simulated data management and visualization for a Pelton turbine study. This work has been done in collaboration with Profs. Avellan, Kueny and Farhat (Laboratory for Hydraulic Machines, EPF-Lausanne) and Etienne Parkinson (VA TECH Hydro SA, now Andritz Hydro). Three papers have been published on this work: one in 2004 and one in 2006 on fluidodynamics and one in 2005 on data management.


  • Added CFX reader
  • Added specialized visualization techniques
  • Added modules to overcome AVS/Express annoyances (like extents on select cell set)
  • Used a lot of validation modules (like computing integrals and surface areas)
  • In depth study of colormaps that helps perception of fine details
  • AVS/Express was mostly a prototyping environment
[CFX logo]

Created the CFX RES Native Format reader for AVS/Express. It is used by the Pelton project.


  • A library from CFX simplified the implementation.
  • A library from CFX introduced a lot of bugs outside our control.
