QES (QUIC EnvSim): fast GPU urban wind, turbulence and dispersion model

Simulation

Open-source successor to LANL's QUIC: a mass-conserving diagnostic wind solver on GPU (QES-Winds), a turbulence closure (QES-Turb) and Lagrangian dispersion (QES-Plume) for building-resolving runs much faster than real time.
