fnrizzi / ElasticShearWaves

Scope

This repository contains code for simulating elastic seismic shear waves in an axisymmetric domain. The implementation uses Kokkos and Kokkos-kernels to enable performance portability, and provides capabilities to run both the full order model (FOM) as well as the Galerkin reduced order model (ROM).

Specifically, this code has been developed mainly for this paper.

Building

To build the code, you can use one of the following two alternatives:

• If you are an "expert" and want to use CMake directly, you can refer to this page.

• If you prefer a more guided procedure where we show you step-by-step how to install the TPLs, and provide you a way to build the code using helper bash scripts that we prepared, you can
  follow this step-by-step guide.

Step-by-step for running a full-order model simulation
