Traditional methods for protecting spacecraft and occupants from harmful radiation in the form of energetic particles from solar and galatic sources involve some configuration of a massive material shield to absorb the energy of incoming particles. Designing a magnetic shield that is strong enough to deflect GCR particles but weak enough to not harm astronauts is a challenge. Investigating possible solutions involves a combination of electromagnetic theory, numerical analysis, engineering practicality, and an astronaut’s sense of exploration.
By using advanced numerical simulation tools and methods we can predict, design and re-design systems to most optimized configuration to protect spacecraft from spacecraft-plasma interactions and electromagnetic waves harmful effects. We can investigate orbital debris impact with advanced finite element tools such as ansys ls-dyna and abaqus for any probabilistic impact problem, also.

Simulation of Complex Systems to Gain Most Optimized Configuration with Advanced Technology
Magnetized plasma simulations of realistic devices using the kinetic or the multi-fluid plasma models are examples that benefit from high-order accuracy. The multi-fluid plasma model only assumes local thermodynamic equilibrium within each fluid, e.g. ion and electron fluids for the two-fluid plasma model.
Plasma Dynamics use advanced electromagnetic FEA, CFD and particle-in-cell (PIC) codes, designed for executing multi-scale, plasma physics simulations. Based on the problem and its detail, we use special commercial code or even develop new codes and subroutines to capture the interaction between charged particles (electrons and ions) and external and self-generated electric and magnetic fields.
