CLAWPACK

Inflow BCs for acoustics

Acoustics equations with zero initial conditions, inflow at x=0, solid wall at x=1.

The inflow boundary conditions are set in bc1.f to be an incoming wave of strength 0.5*sin(ωt). The value of omega is specified in setrun.py.

Note that after time 2π ⁄ ω the boundary conditions at the left are replaced by extrapolation (outflow) boundary conditions.

Example [book/chap7/acouinflow] to accompany the book Finite Volume Methods for Hyperbolic Problems by R. J. LeVeque.
