Kinetic plasma simulation with PICLas
boltzplatz utilizes the plasma simulation software PICLas, developed by the University of Stuttgart at the Institute of Aerodynamics and Gas Dynamics and the Institute of Space Systems. PICLas allows the prediction of rarefied gas and plasma dynamics under the influence of electromagnetic forces. The code is freely available under the GNU General Public License v3.0 and if you want to participate in the development, contact us!
To treat electromagnetic or electrostatic interaction, Maxwells or Poissons equations are solved with a high-order discontinuous Galerkin solver. The mixed finite-element-finite-volume scheme combines the advantages of both methods. It enables an efficient and scalable parallelization concept optimized for high-performance computing, reducing the time-to-solution. Find out more...
With the goal of the approximation of the complete Boltzmann equation in mind, a flexible three-dimensional code framework for particle methods was devised. These methods can be coupled or used stand-alone such as Particle-in-Cell (PIC) for the electromagnetic interaction, Direct Simulation Monte Carlo (DSMC) for non-equilibrium, high-enthalpy gas & plasma flows in the high Knudsen number regime, Bhatnagar-Gross-Krook (BGK) for gas flows close to the continuum regime.
