Part II: Continental-scale Simulations

This second part of the tutorial will take you through the steps that are needed to run a continental-scale simulation with SPECFEM3D_GLOBE. The steps we need to take are the following:

Prepare the Data and Parameters

As we talked about in the previous part of the tutorial, the parameter files for the SPECFEM3D_GLOBE package are found in the DATA/ folder. In order to set up the simulation, we need to:

  1. Provide the source characteristics for the event we want to simulate
  2. Provide names and locations for the stations we want to use
  3. Set the relevant simulation parameters in the Par_file

NOTE: As mentioned in the previous section, if you make any changes to the Par_file after compiling SPECFEM3D_GLOBE, you need to recompile the package by running make clean and make all in the root folder.

In this section, we have looked at how to provide the input data that is necessary to run a continental-scale simulation with SPECFEM3D_GLOBE.

In the next section, we will look at how to generate a mesh for the continental-scale model.
