Abstract
A constructive version of the discontinuous Galerkin method (DGM) of arbitrary orders of accuracy to solve gasdynamic (GD) equations is proposed. This DGM is based on the new variational principle of entropic regularization ensuring the implementation of discrete analogs of the conservation laws of mass, momentum, total energy, and entropic inequality.
