The Ongoing Development of Distributional Finite-difference Modeling in Global Seismology
DFDM was recently introduced as a new numerical simulation approach that combines advantages from classic finite difference and finite element methods for solving the elastic wave equation (Masson, 2022). Through two/three-dimensional benchmarks against the well-established spectral element method (SEM) in Matlab, we have demonstrated this algorithm's high level of precision, at reduced computational cost with the flexibility to describe the meshing. We recently started a collaboration with the Application Performance Group at NERSC to develop a distributed version of the solver in C++ optimized for use on HPC platforms.
