AxiSEM3D - Fast, Efficient Seismic and Acoustic Synthetics for Complex 3D Models
Description:
The AxiSEM3D method is a coupled pseudospectral-spectral element method which allows for efficient computation of synthetic seismograms in complex 3D models on global, regional, and local scales. It is a fully 3D version of the original, 2.5D AxiSEM method.
The code has recently been updated and now supports propagation of seismic and acoustic waves at global frequencies up to several Hz (on HPC architectures), for structural models including the Earth, Moon, Mars, and Sun. Additional functionality supported includes volumetric and topographic (surface and interior) models, fluid oceans, strong off-plane scattering, and atmospheres.
In this work we will illustrate some pertinent use cases across Earth and Solar System environments, and share recently-developed user guides and manuals designed to simplify the user experience whilst preserving computational efficiency.
