PHARE is a Hybrid Particle-In-Cell (PIC) code. It solves the evolution of the Vlasov equation of an arbitrary number of ion populations in a Lagrangian way. Electrons are modeled as a single fluid. Their momentum equation is used to compute the electric field, assuming quasineutrality.

Using Adaptive Mesh Refinement, provided by the library SAMRAI, PHARE aims at filling the gap between sub-ion scales and large "MHD" scales by increasing the mesh resolution wherever the solution needs it.

PHARE is still under development.

PHARE is an open-source projet licenced under the GPLv3. Please refer to LICENCE.TXT

For system library requirements see the following Docker File

For Python API, install dependencies:

  python3 -m pip install -r requirements.txt

Build with CMake and latest SAMRAI:

  mkdir build; cd build; cmake ..; make

Build with CMake and specific SAMRAI:

  mkdir build; cd build; cmake .. -DSAMRAI_ROOT=/path/to/SAMRAI/install; make

All contributions are welcome, although the code is still at an early phase of its development. If you are interested in participating to the project for an internship, PhD, PostDoc, contact us.
