A componentized approach to grid enabling seismic wave modeling application

The attention to Arctic shelf is explained by the real need of exploration and development of oil-fields and gas-fields. The computer modeling is a single appropriate approach because the physical experiments in Arctic are expensive and sometimes ...

When applied to wave propagation modeling in anisotropic media, Perfectly Matched Layers (PML) exhibit instabilities. Incoming waves are amplified instead of being absorbed. Overcoming this difficulty is crucial as in many seismic imaging applications, ...

Solving for the scattered wavefield is a key scientific problem in the field of seismology and earthquake engineering. Physics-informed neural networks (PINNs) developed in recent years have great potential in possibly increasing the flexibility ...

• Inspired by SA-PINNs, we introduce a framework for modeling seismic waves in complex topography.
• Combined with the sparse initial wavefields, enables high-precision simulation.
• A time-domain decomposition scheme was proposed to ...
