 A brief summary of the history: the development of a particle code was started by Chao Li, who developed a hybrid particle/fluid code. Margreet Nool restructured this code, from which Jannis Teunissen then extracted just the particle part. To be able to do meaningful simulations with just particles, much had to be changed and essentially all the code was rewritten by Jannis. Later, Anbang Sun has contributed to parts of the code. A brief summary of the history: the development of a particle code was started by Chao Li, who developed a hybrid particle/fluid code.

 We use a particle-in-cell (PIC) approach, with tri-linear interpolation to map particles to densities, also known as cloud-in-cell (CIC). We use a particle-in-cell (PIC) approach, with tri-linear interpolation to map particles to densities, also known as cloud-in-cell (CIC).
-As a particle mover we use the so-called velocity-verlet scheme. For electron-neutral collisions, we use the null-collision method. For a description of the adaptive particle management that we use, see this paper [[http://homepages.cwi.nl/~ebert/JCPJannis2014.pdf]].+As a particle mover we use the so-called velocity-verlet scheme.

 +The code depends on the following external libraries, which are distributed along with the code: 
 +  * [[https://www2.cisl.ucar.edu/resources/legacy/fishpack|Fishpack]] 
 +  * [[https://wci.llnl.gov/codes/silo/|Silo]] 
 +  * [[http://arxiv.org/abs/physics/0408067|KDTREE2]] 
 + 
 +Furthermore, you need to have a working MPI installation with development files, such as openmpi or mpich, and a Fortran compiler. 
 + 
 +To compile, execute the following commands: 
 +<code> 
 +$ git submodule init 
 +$ git submodule update 
 +$ make 
 +</code> 
 + 
 +Running (sequential): 
 +<code> 
 +$ ./pampi3d my_config_file.txt 
 +</code> 
 + 
 +Running (parallel, N = number of tasks): 
 +<code> 
 +$ mpirun -n N ./pampi3d my_config_file.txt 
 +</code> 
 + 
 +You can also specify multiple configuration files, like: 
 +<code> 
 +$ ./pampi3d cfg_base.txt cfg_1.txt 
 +</code> 
 + 
 +This should((hopefully)) work with newer versions (> 4.4) of [[https://gcc.gnu.org/wiki/GFortran|gfortan]].
