An implicit numerical method is described for treating the coupled evolution of a stellar system and interstellar gas in spherical geometry. Gas model equations of a stellar system are formulated in a manner similar to the usual gas dynamical equations. A simple approximation for the transfer of radiation is included. The resulting system of difference equations is solved implicitly by a standard Newton-Raphson-Henyey method. The method is designed to be applicable for a broad range of problems. Thus, it makes it possible to take into account various features such as heating and cooling processes of the interstellar medium, mass exchange between stars and gas by stellar mass loss or disruptive stellar collisions, the effect of velocity anisotropy and relaxation processes in the stellar system, and the exchange of kinetic internal energy between the stellar system and the interstellar gas via drag forces. As an example, the method is applied to the evolution of a dense gas-star system contained in a galactic nucleus.
