Numerical Simulations Can Lead to New Insights

. Numerical simulations can lead to new insights into astrophysical processes that would be difficult to achieve otherwise. We present a few examples from our 1.5D radiation-magneto-hydrodynamic calculations and 3D convection calculations: 1. Magnetic field free regions of the chromosphere have enhanced emission without any increase in the average gas temperature. 2. Solar convection is driven non-locally by cool, turbulent, filamentary, downdrafts produced by radiative cooling in the surface boundary layer. 3. The lower part of the solar convection zone is slightly stably stratified. 1. Introduction Numerical simulations can lead to new insights into astrophysical processes that would be difficult to achieve otherwise. We present a few examples from onedimensional radiation hydrodynamic and three-dimensional magneto-hydrodynamic simulations of the solar atmosphere and convection zone. 2. Solar Chromosphere To model dynamics of the solar atmosphere we solve the 1.5-dimensional conse..
