Particle in Cell Method, written in C++

Installation

You will need a C++ compiler, for example gcc, as well as the Eigen library installed on your system. Make sure that the directory /usr/include/Eigen exists on your system, if not you can create a symlink to where Eigen was installed, usually it is /usr/include/eigen3

ln -s /usr/include/eigen3 /usr/include/Eigen

Now you are all set, just run make in the root directory and the code should compile. With make run you can run a test case from the tests directory. Check out the Makefile to see how to use libcpic in your own code.

• phi_analytic is the analytic solution
• phi_BR is the Boltzmann-electron model solution
• phi_GA is the fully kinetic solution using Garcia's infolow boundary condition
• phi_GC is the fully kinetic solution using the ghost cell inflow boundary condition
