Parallel multiphysics simulation of the attraction of homogeneously charged particles in fluid flow by an oppositely charged surface and their deposition on that surface.

The simulation was performed by coupling the HPC software framework waLBerla (for the flow) to the physics engine pe (for the particles).

The electric field was modeled as gradient of an electric potential governed by Poisson's equation solved by means of a cell-centered multigrid solver implemented in waLBerla.

More details on this lattice Boltzmann based simulation are given in the paper https://doi.org/10.1016/j.jocs.2015.02.006
