SoLID Software Detector Simulation
Contents
"solid_gemc" general info
SoLID detector simulation program "solid_gemc" is based on "GEMC" with additional hit process routine and outputs for all detector systems in SoLID.
It's located SoLID repository https://jlabsvn.jlab.org/svnroot/solid/solid_gemc2 with source codes and detector configuration, field, scripts etc.
You need both the jlab framework and SoLID repository before you have compile and run solid_gemc, refer to the installation section
quick start
setup
All env variables required are setup by source file "set_solid"
make sure you meet the requirement here
The example below demonstrates how to setup in various cases.
on ifarm with official installation of framework and SoLID repository (demonstration)
The fastest way to see what the simulation look like. You don't need to install any thing, but you can't modify anything either.
login into ifarm with your account source /home/zwzhao/solid/solid_svn/solid/set_solid follow "compile and run" to run it (skim compiling)
on ifarm with official installation of framework and your SoLID repository (recommended)
You don't need to install the framework, you can modify simulation configuration. This is the best way to run simulation on ifarm and farm nodes. This is recommend way to compare result and produce results.
cd your_choice_of_solid_repo_path svn co https://jlabsvn.jlab.org/svnroot/solid cd solid edit file set_solid by following the instruction within, you only need to change SoLID_GEMC source set_solid follow "compile and run" to compile and run it
on any machine with your installation of framework and your SoLID repository (expert)
This gives you maximum freedom to use any version of framework and ability to work on your local machine, And allow you to modify anything. This is the way to run on your local machine.
install the framework by following installation instruction cd your_choice_of_solid_repo_path svn co https://jlabsvn.jlab.org/svnroot/solid cd solid edit file set_solid by following the instruction within source set_solid follow "compile and run" to compile and run it
compile and run
Once you complete the setup procedure, you can now compile "solid_gemc"
cd $SoLID_GEMC/source scons OPT=1 you need to recompile every time GEMC gets updated
after compiling, do the following to run it
cd $SoLID_GEMC/script solid_gemc solid_PVDIS_LD2.gcard or solid_gemc solid_PVDIS_simple.gcard solid_gemc solid_SIDIS_He3.gcard or solid_gemc solid_SIDIS_He3_simple.gcard solid_gemc solid_SIDIS_NH3.gcard or solid_gemc solid_SIDIS_NH3_simple.gcard

general note
https://eic.jlab.org/wiki/index.php/Detector_simulation_general_note
This is general note for GEMC about geometry, materiel, hit processing etc, read it before you proceed to the specific topic below
geometry
refer to file " $SoLID_GEMC/geometrychangelog" for details
source your set_solid cd $SoLID_GEMC/geometry edit perl files to modify geometry, then run command below to generate new geometry txt files ./solid_PVDIS_simple.pl config_solid_PVDIS_simple.dat ./solid_PVDIS_LD2.pl config_solid_PVDIS_LD2.dat ./solid_SIDIS_He3_simple.pl config_solid_SIDIS_He3_simple.dat ./solid_SIDIS_He3.pl config_solid_SIDIS_He3.dat ./solid_SIDIS_NH3_simple.pl config_solid_SIDIS_NH3_simple.dat ./solid_SIDIS_NH3.pl config_solid_SIDIS_NH3.dat
materials
source your set_solid cd $SoLID_GEMC/geometry edit the perl file "solid_material.pl" to modify geometry, then run command below to generate new material txt files ./solid_material.pl config_solid_PVDIS_simple.dat ./solid_material.pl config_solid_PVDIS_LD2.dat ./solid_material.pl config_solid_SIDIS_He3_simple.dat ./solid_material.pl config_solid_SIDIS_He3.dat ./solid_material.pl config_solid_SIDIS_NH3_simple.dat ./solid_material.pl config_solid_SIDIS_NH3.dat
hit processing

simulation for sub-detector systems
"solid_gemc" can be used for the whole detector simulation and individual sub-detector systems at the same time.
Each of sub-detector systems can do simulation independently and ready to merge it back into the whole system simulation.
