Class StrongWaveOperator

source code

This operator discretizes the Wave equation ∂tt u = c^2 Δ u.

To be precise, we discretize the hyperbolic system

∂t u - c div v = 0
∂t v - c grad u = 0

The sign of v determines whether we discretize the forward or the backward wave equation.

c is assumed to be constant across all space.
