Detailed Description

Problem generator for plane-parallel, grid-aligned linear wave tests with Lagrangian particles.

PURPOSE: Problem generator for plane-parallel, grid-aligned linear wave tests with Lagrangian particles. Works only for 2D grid and with wavevector parallel to grid. Particles can be initialized either with uniform density or with the same density profile as gas.

Can be used for either standing (problem/vflow=1.0) or travelling (problem/vflow=0.0) waves.
