PINNs for simulating 2D seismic wave propagation

This example uses PINNs for emulating 2D time-dependent seismic wave propagation using a simple domain geometry.

Problem overview

This sample illustrates how to solve the acoustic wave equation You can get more details on this sample from the documentation

Dataset

This example does not require any dataset as it solves of the acoustic wave equation, the physical geometry and the boundary conditions.

Model overview and architecture

We use a simple fully connected MLP to approximate the solution of the 2D time-dependent wave equation for the given boundary conditions. The neural network will have x, y and t inputs and u, c (pressure response and velocity) and outputs .

Getting Started

To get started, simply run

python wave_2d.py
