Important
This is a beta release. Development is still in progress, and various bugs may be present. Minor changes to the user interface can still occur.
Welcome to chombo-discharge’s user documentation
Important
chombo-discharge is a modular and scalable research code for Cartesian two- and three-dimensional simulations of low-temperature plasmas in complex geometries.
The code is hosted at GitHub together with the source files for this documentation.
chombo-discharge features include:
Fully written in C++.
Parallelized with OpenMP, MPI, or MPI+OpenMP.
Support for complex geometries.
Scalar advection-diffusion-reaction processes.
Electrostatics with support for electrodes and dielectrics.
Radiative transport as a diffusion or Monte Carlo process.
Particle-mesh operations (like Particle-In-Cell)
Parallel I/O with HDF5.
Dual-grid simulations with individual load balancing of fluid and particles.
Various multi-physics interfaces that use the above solvers.
Various time integration schemes.
Numerical solvers are designed to run either on their own, or as a part of a larger application.
For scalability, chombo-discharge is built on top of Chombo 3, and therefore additionally features
Cut-cell representation of multi-material geometries.
Patch based adaptive mesh refinement.
Weak and strong scalability to thousands of computer cores.
Our goal is that users will be able to use chombo-discharge without modifying the underlying solvers.
There are interfaces for describing e.g. the plasma physics, boundary conditions, mesh refinement, etc.
As chombo-discharge evolves, so will these interfaces.
We aim for (but cannot guarantee) backward compatibility such that existing chombo-discharge models can be run on future versions of chombo-discharge.
