IonSolver is a magnetohydrodynamic simulation software featuring an extended Lattice Boltzmann method and GPU acceleration

IonSolver

This software will attempt to model magnetohydrodynamic processes with magnetic field-ionized gas interactions. It uses a lattice-boltzman-model for the fluid, initial kernel functions for the LBM where taken with permission from the software FluidX3D by Dr. Moritz Lehmann. IonSolver is still in development, with a GPU-accelerated fluid simulation implementation and the basics of magnetohydrodynamics + a basic GUI app functional. A more accurate coupled implementation of electrodynamic effects on the simulated fluids is in the works.

Usage

To run this software, clone this repository, install rust if not installed already, and run the command cargo run --release
