2015 PyLith Modeling Tutorial (virtual)

Adobe Connect

Announcement for the 2015 PyLith Modeling Tutorial

This virtual workshop will focus on providing training in the use of the CIG PyLith software for quasi-static modeling of crustal deformation, with an emphasis on interseismic, coseismic, and postseismic deformation. The training will also include instruction in CUBIT/Trelis for creating finite-element meshes as input for PyLith and visualizing PyLith output using Paraview.

This two-day virtual workshop will be held Monday August 24 - Tuesday August 25, 2015, using AdobeConnect web-based tools. Each of the two days will be divided into 2 hour sessions with morning (Pacific Time) and afternoon (Pacific Time) sessions. There are no registration fees.

Workshop Information



  • Brad Aagaard (USGS)
  • Charles Williams (GNS Science)
  • Matthew Knepley (Rice University)


Users will need

  • a computer with speakers (headphones are strongly recommended) and a microphone (optional),
  • high-speed internet access, and
  • a web-browser capable of displaying Flash content (including audio).

The training will be provided via Adobe Connect meeting software through your web browser. We will be using VoIP for the audio via Flash, so you will need speakers and, optionally, a microphone that work with your Flash plugin of your web browser. We strongly recommend that you test your browser and become familiar with Adobe Connect before the tutorial using the links below. We recommend Firefox or Chrome web browsers; we have encountered problems loading Adobe Connect on Linux x86_64 systems with Firefox but not with Chrome. Detailed instructions for the online sessions will be emailed to registered participants before the workshop.


We request all participants download and install PyLith, CUBIT/Trelis, and ParaView on your computer before the workshop. See workflow diagram for a general description of the typical workflow used in numerical modeling of crustal dynamics
  • PyLith - static, quasi-static, and dynamic crustal deformation

    Binary packages and the PyLith manual are available on the PyLith webpage. The manual has a troubleshooting section, and there are links to the cig-short mailing list where users can get assistance.

  • CUBIT/Trelis - finite-element meshing

    csimsoft has created their own version of CUBIT, called Trelis. Sandia National Laboratories continues to provide CUBIT releases to US government agencies.

    Users can download a 30-day free trial version of Trelis from csimsoft. Registering for the free trial version can take several hours to a day before you can download the software.

  • ParaView - visualization

    ParaView is a GUI visualization tool discussed in the PyLith examples. Binaries are available for a wide variety of platforms on the ParaView website. Click on RESOURCES->Download. Use version 4.3.1.
