---++ The simulation framework

The FOOT simulation is performed using the [[http://www.fluka.org/fluka.php][FLUKA software package]] and the <a href="https://geant4.web.cern.ch" target="_blank">Geant4</a> code.
---++ Running the simulation: how to

There are several steps needed to get, compile, run, access the simulation output.
---+++ Getting the code

The instructions to download the code are available in the [[FOOTSoftware][FOOT software page]].
---+++ Compiling and running

As a prerequisite for running a simulation with FLUKA you need a valid installation of the FLUKA software.

You have to setup the $FLUPRO, $FLUTIL and $FLUFOR variables before compiling the code (help with the FLUKA installation phase is provided in the [[http://www.fluka.org][FLUKA web page]], FLUKA mailing lists and, if everything else failed, from the FOOT FLUKA "experts": V. Patera, G. Battistoni, A. Sarti). Once everything is installed and setup, you can compile the code and run the simulation. Instructions can be found in the following presentatation [[%ATTACHURL%/FOOT_simulation.pdf][FOOT_simulation.pdf]].

To run simulation with Geant4, you need to install the Geant4 software (see the <a href="https://geant4.web.cern.ch/support/download" target="_blank">download</a> page of the Geant4 collaboration).

The FOOT software needs to be installed by adding the option -DGeant4_DIR=G4BUILD in the cmake command, before compiling SHOE. The G4BUILD variable points to the path to the build directory of your Geant4 installation. the Geant4 source simulation files for FOOT is located in the trunk/G4simulation directory of SHOE.

To compile the FOOT simulation, go in the build/G4simulation directory, than the simulation can be executed with the %GRAY%TAGsimulation%ENDCOLOR% command (don't forget to switch on/off the detectors you want to simulate in the FootGlobal.par file located in the build/G4simulation/config directory). In case of problems, do not hesitate to contact M. Vanstalle.

To learn more about running Geant4 simulation on SHOE, see <a href="http://arpg-serv.ing2.uniroma1.it/twiki/pub/Main/FOOTSimulation/FOOT_Geant4.pdf" target="_blank">FOOT_Geant4.pdf</a>

To learn more about how to use Geant4, see the <a href="http://geant4-userdoc.web.cern.ch/geant4-userdoc/UsersGuides/ForApplicationDeveloper/html/index.html" target="_blank">User's Guide</a> on the Geant4 website, or <a href="http://arpg-serv.ing2.uniroma1.it/twiki/pub/Main/FOOTSimulation/G4lecture.pdf" target="_blank">G4lecture.pdf</a>.
---+++ Event reconstruction

The reconstruction of the decoded MC events is accomplished using the reconstruction software [[FOOTReconstruction][documented in the related web page]].

Starting from May 2020 an update of the input root format has been provided by C. Finck. It is now possible to use the Txt2NtuRoot executable in the bin folder to process the output from FLUKA (dat files) and produce a root file that contains directly the tupled TAG* classes. Oncec you have the root files with the root objects, to process them while using the DecodeMC executable, you *need to pass the -obj flag*.
---+++ Presently available simulation output files

On the tier3 there are Root output files of simulation available as reference for the study of detector performances. They are [[FOOTAvailableSimulation][documented in the related web page]]
