This tutorial demonstrates how to prepare meshes for global seismic wave simulations using the anisotropic adaptive mesh refinement rechnique (aamr), which in this context is also known as smoothiesem [1, 2]. The meshes are specifically build for a particular source location to take advantage of the lateral smoothness of the wavefield and reduce the numerical burden significantly for global and regional scale simulations.
The mesh can be refined in predefined depth, distance and azimuth regions. Additionally, the domain can be restricted to a region of interest as discussed in the separate data adaptive mesh masking tutorial.
In this tutorial we demonstrate the basic concept and most important parameters to build these meshes.
