Transport of phase space densities through tetrahedral meshes using discrete flow mapping
Janis Bajars, David Chappell, Niels Sondergaard +1
Discrete flow mapping was recently introduced as an efficient ray based method determining wave energy distributions in complex built up structures. Wave energy densities are trans…

Discrete flow mapping: transport of phase space densities on triangulated surfaces
David Chappell, Gregor Tanner, Niels Sondergaard +1
Energy distributions of high frequency linear wave fields are often modelled in terms of flow or transport equations with ray dynamics given by a Hamiltonian vector field in phase…
