Computer simulations we conduct originate strongly from the research activities conducted in collaboration with partners like CERN, Uppsala University and Helsinki University. Main research activities stand in modeling of the electrochemical energy storage and investigation of vacuum breakdowns in high electric field RF systems (sparks on electrodes). Used methodology covers DFT, molecular dynamics, Finite Element Analysis and includes multi scaling capacity (combined electrodynamics, molecular dynamics).
Figure 1 Multiscale simulations of nanoparticle contact. Combined atomistic and FEM analysis.
Examples of our simulations capacity include (from finite element analysys): Mechanics, CFD (turbulent & laminar), Heat transport, Electric and magnetic fields, Chemical reactions, Acoustics. Most significant is the Multiphysics combinations of these phenomena!

Some of our previous experience include simulations of large plastic deformations, topology optimization (for mechanical loads and electric fields), post mortem analysis of IGBT transistor contacts (combined heat, electric currents, thermal stresses), design of industrial scale kilns (CFD, heat and moisture transport, drying dynamics), magnetic signature analysis of naval vessels.

Our unique simulation capacity, developed together with Helsinki University includes capacity for material-electric field interactions in DC/AC conditions, including RF frequencies, emission current calculations, vacuum arcs, atomistic scale material damage evolution, radiation damage and nanoscale thermomechanical behaviour. Work is done in for vacuum breakdown (vacuum arc) studies in CERN, CLIC accelerator design. The combined Electrodynamics – Molecular Dynamics (EDMD) simulations allow simutaneous calculation of atomic response, applied electric fields, temperature distributions and emissioon currents.
