Numerical Simulation and Diagnostics in Astrophysics

We discuss some issues related to numerical simulations in Astrophysics and, in particular, their use both as a theoretical tool to gain insight into the physical phenomena at work, and as a diagnostic tool.

We illustrate our point presenting some simulations of astrophysical plasmas and illustrate their use both for theory and diagnostics. In particular we show the need for appropriate tools to visualize and present results in an adequate form, and the importance of spectral synthesis for a direct comparison with observations.
