The Software and Computing Task Force also provides the tools for Monte Carlo simulation of the experiment.
There are several simulations packages currently used or under development:
flyo
Originally from Giuseppe Pierazzini, C++ single-particle simulation of the full K+ to pi+ nu anti-nu experiment

Geant3 based simulation of the full setup, from Oleg Yushchenko
- Fortran Monte Carlo:
Manual
- ROOT-based:
Disclaimer
- Proposal layout! [Double spectrometer]
- Large Angle Veto: only lead/scintillator tile implemented
- Simplified digitization
- Not updated straw chambers layout
- RICH not implemented

Virtual Monte Carlo and ROOT-based framework for simulation, from Oleg Yushchenko

Geant4 Photon Vetoes simulations from
RomaGroup +
NapoliGroup

Toy Monte Carlo of RICH from Firenze Group
