2D Simulations of Stellar Convection. II. A Study of the Dependence of the Results on Numerical Methods

Models of a 2-D convectively unstable layer placed between two stable layers are obtained using two independent numerical codes. Penetration ranges and mechanical energy fluxes carried by internal gravity waves are measured for several models with different global parameters. It is shown that both codes produce statistically identical results, which makes them reliable tools for investigations of stellar convection.
