The Panda experiment at the future FAIR facility at GSI Darmstadt will investigate anti-proton proton and anti-proton nucleus collisions with beam momenta in the range from 2 GeV/c to 15 GeV/c. In order to a.) simulate the detector performance for physics and b.) to evaluate different detector concepts a modular software framework for simulation, reconstruction and data analysis is being developed, which is based upon ROOT and is called PandaRoot. Several event generators are implemented (e.g. EvtGen, Pluto, UrQmd). The use of Virtual Monte Carlo (VMC) allows the user to easily switch between different transport models, such as Geant3 and Geant4. The configuration of an application is fully handled using ROOT-scripts. In addition, the software framework is successfully running on an AliEN2-based GRID network layer. Preliminary simulations and reconstruction results will be presented for charmonium-rich reaction channels, such as p p → Y(4260) → J/Ψ π+ π− and p p →
hc → ηc γ → η π0 π0 → γ γ γ γ γ γ γ, polarized decays, such as p p → Λ Λ, and for the production and decay of hypernuclei.
