Query: A Boltzmann scheme with physically relevant discrete velocities for
  Euler equations   Kinetic or Boltzmann schemes are interesting alternatives to the macroscopic
numerical methods for solving the hyperbolic conservation laws of gas dynamics.
They utilize the particle-based description instead of the wave propagation
models. While the continuous particle velocity based upwind schemes were
developed in the earlier decades, the discrete velocity Boltzmann schemes
introduced in the last decade are found to be simpler and are easier to handle.
In this work, we introduce a novel way of introducing discrete velocities which
correspond to the physical wave speeds and formulate a discrete velocity
Boltzmann scheme for solving Euler equations.
