GeFiCa stands for Ge detector Field Calculator. It provides classes to calculate static electric fields and potentials in Ge detectors using various coordinates in up to three dimensions. The field potential values together with their grid coordinates are saved in a ROOT tree to take the advantage of the file compression and the Draw function provided by the ROOT TTree class. GeFiCa is provided as a shared library that can be directly loaded by ROOT. All GeFiCa classes can be used directly in a ROOT interactive session or a Jupyter notebook. Users can modify and run their calculation codes without compilation.

GeFiCa contains a Git submodule of MJD fieldgen. It is a mirror of the MJD siggen (including fieldgen) subversion repository in GitHub. The mirroring is done by
apt install git-svn
git svn clone https://radware.phy.ornl.gov/MJ/mjd_siggen/ siggen
git remote add origin [email protected]:jintonic/siggen.git
git push origin masterAdding it as a git submodule to GeFiCa is done by
cd /path/to/GeFiCa
git submodle add https://github.com/jintonic/siggen.git examples/pointContact/fieldgen
git commit -m "added siggen submodule"
git pushCloning GeFiCa with fieldgen can be done by doing
git clone https://github.com/jintonic/gefica.git
cd gefica
git submodule init
git submodule updateUpdating GeFiCa and fieldgen can be done by doing
cd gefica
git pull
cd examples/pointContact/fieldgen
git pull
