==== Overview ====

This site provides download and installations instructions for the - [[ https://geodynamics.org/cig/events/calendar/2018-cgu-cig/aspect-tutorial/|CGU 2018 Introduction to Modeling Lithospheric Dynamics Tutorial]].

The tutorial utilizes the mantle convection and lithospheric deformation code [[https://geodynamics.org/cig/software/aspect/|ASPECT]], which has been precompiled on a virtual machine along with other software. The virtual machine will be run with VirtualBox.

Please note that all of the required software and files should be downloaded and installed ***BEFORE*** the tutorial.

If you have any questions about the tutorial or problems arise with the software installation please contact help@geodynamics.org.

==== Tutorial Prerequisties ====
=== Virtualbox ===

You can download VirtualBox [[https://www.virtualbox.org/wiki/Downloads|here]] and please use [[https://www.virtualbox.org/manual/ch02.html|these directions]] to install VirtualBox.

If your host machine is any linux system, both ''virtualbox'' and ''virtualbox-dkms'' packages must be installed. Also check to make sure you have exFAT filesystem drivers. Windows and Mac systems should have it by default. On Ubuntu, the packages required are ''exfat-utils'' and ''exfat-fuse''.

We recommended that your computer have at least 20 to 30GB of free disk space and preferably 4GB of RAM.

=== Tutorial Image ===

We will use virtual box to boot up a ubuntu 14.04 linux OS image titled ASPECT-tutorial-2.0.ova.

This image contains the following software packages pre-installed:
  * ASPECT
  * dealII
  * Paraview

Please [[https://geodynamics.org/cig/static/CGU18-aspect-tutorial.ova|download ASPECT-tutorial-2.0.ova]] onto laptop you are going to use for the tutorial. The image is ~2.6 Gb, so please allow plenty of time for the download and use a high-speed internet connection if possible.

=== Importing the CGU18 tutorial image ===

  - Run VirtualBox.
  - **Select from the menu "Import appliance"**: {{:cgu18_select_import_appliance.png?nolink|}}
  - **Select the downloaded ASPECT-tutorial-2.0.ova**: {{:cgu18_select_vm_image.png?nolink|}}
  - **Select Continue and Import**: {{:cgu18_import_vm.png?nolink|}}
  - **Click on start (the green arrow) to launch the image**: {{:cgu18_start_green_arrow.png?nolink|}}


=== Using the Image ===


Now simply start the ASPECT-tutorial virtual machine.
