GEMPIC: Geometric ElectroMagnetic Particle-In-Cell Methods [PDF]
, 2017 We present a novel framework for Finite Element Particle-in-Cell methods based on the discretization of the underlying Hamiltonian structure of the Vlasov-Maxwell system. We derive a semi-discrete Poisson bracket, which retains the defining properties of

Dual Virtual Element Methods for Discrete Fracture Matrix models
Oil & Gas Science and Technology, 2019 The accurate description of fluid flow and transport in fractured porous media is of paramount importance to capture the macroscopic behavior of an oil reservoir, a geothermal system, or a CO2 sequestration site, to name few applications.

Discrete-element-method model for frictional fibers
Physical Review E, 2023 We present a Discrete Element Method algorithm for the simulation of elastic fibers in frictional contacts. The fibers are modeled as chains of cylindrical segments connected to each other by springs taking into account elongation, bending and torsion forces.
