abstract = {<p style="text-align: justify;">We present the development of a non-reflecting boundary condition, based
on the Local One-Dimensional Inviscid (LODI) approach, for Lattice Boltzmann Models working with multi-speed stencils.<br/>We test and evaluate the LODI implementation with numerical benchmarks, showing significant accuracy gains with respect to the results produced by a simple zero-gradient condition. We also implement a simplified approach, which allows handling
the unknown distribution functions spanning several layers of nodes in a unified way,
still preserving a comparable level of accuracy with respect to the standard formulation.</p>},
