2015 summer Program Tutorials

Laurent Montesi. Geodynamics tutorial: Mantle convection with ASPECT

In this tutorial, we will conduct simple basic convection models that are used to learn about the physics of mantle convection. We will be using the FInite Element code ASPECT [1], developed by CIG [2]. You should have downloaded a virtual machine that contains the code before coming to CIDER (certainly before the tutorial!). We will work on installing the virtual machine, study the code, its input file, and how to visualize the results. We will work together to construct the relation between Rayleigh number and Nusselt number (I will explain what that means) for different grid resolutions.

The specific tutorial objectives are

  > Understand better numerical modeling
  > Learn basic use of the ASPECT code
     >>Command line operations
     >>Equations for mantle convection 
  > Edit parameters for an ASPECT simulation
     >>Boundary conditions
     >>Grid refinement
  > Visualize ASPECT output using Paraview
  > Analyze ASPECT simulation results
  > Document the Nusselt-Rayleigh number relation

Paul Asimow. MELTS

For Thursday 9 July afternoon, here is an updated version of the Melts-rhyolite executable. Please put this in your ~/MELTS folder on your virtual machine: http://www.asimow.com/Melts-rhyolite-public.zip

Doug Wiens: Seismology tutorial

We will be using the SEATREE modules larry3d, larry, and Syn2D Seatree is available at http://geosys.usc.edu/projects/seatree/

The software has been put in a virtual machine: http://geodynamics.usc.edu/~becker/ugesce.html This is a different virtual machine from the one with CIG used in other tutorials. It needs to be downloaded separately from what you've done before.

You can download the virtual machine from the link above or you can copy it off of a memory stick that Doug Wiens can give you. You should try to do this prior to the tutorial. The virtual box requires about 13 Gb of disk space when uncompressed, so you may need to clear off your disk drive a little. If your disk space is extremely limited you may have to share a computer with somebody else.

After you have installed the compressed software, click it to uncompress. You should then find another virtual machine named "Seatree-2015" on your virtual box manager (along with the Cider one). Double click this virtual box (or click on the green arrow with it selected) to start Seatree.

You will then get a login screen. Login as "Seatree user" with password "seatree"
