“…The new low-dissipation numerical scheme for solving equations of magnetic gas dynamics with consideration of chemical processes and its software implementation are presented in the paper. The numerical method is based on hybrid method developed earlier with combination of operator splitting approach and Godunov method in its basis (Tutukov et al 2011;Vshivkov et al 2009Vshivkov et al , 2011aGodunov & Kulikov 2014;Kulikov 2014;Kulikov et al 2015a,b,c;Kulikov & Vorobyov 2016;Protasov et al 2016). The piecewise-parabolic method on local stencil is used in all stages of the scheme to get low dissipation of the solution.…”

The new code for numerical simulation of magnetic hydrodynamical astrophysical flows with consideration of chemical reactions is given in the paper. At the heart of the code -the new original low-dissipation numerical method based on a combination of operator splitting approach and piecewise-parabolic method on the local stencil. The details of the numerical method are described; the main tests and the scheme of parallel implementation are shown. The chemodynamics of the hydrogen while the turbulent formation of molecular clouds is modeled.
