G2C3 (Global Gyrokinetic Code using Cylindrical Coordinates) is a particle-in-cell (PIC) code developed at the Plasma Theory Group (PTG) at the Indian Institute of Science (IISc) to study kinetic instabilities in magnetically confined fusion plasma. This wiki page serves as a manual for G2C3 (Ver1.0).

The literature on the gyrokinetic simulation codes are in here.

>> make clean
>> make
>> make sc

>> make run

We use a ''Makefile'' to compile the code configured to run different compilers based on the HPC system and to run the code using the ''jobscript''. If you are setting up the code to run on a new machine, please follow the instructions to modify the Makefile and the jobscript as required.

• The input data is stored in “./dat/” folder.
• The output files are written into “./output/” folder.
• The input parameters for the code are read from “./dat/G2C3.in” file.
• The time stamps at each iteration's end are written into “Time.out”.
• Writing output data is performed in “write_data.F90”.
• The output and diagnostic data are written once every “snap_interval” iteration.

System Requirement: MATLAB 2024b (and above)

The MATLAB app installation files are available in “./gui” folder. Go to the MATLAB “APPS” tab, click “Install App” and choose the corresponding files.
