Smoothed Particle Hydrodynamics in pkdgrav3 for Shock Physics Simulations. II. Shear Strength
Thomas Meier, Christian Reinhardt, Martin Jutzi +2
Material strength effects have been recently shown to be significant in giant impacts even at scales of planetary collisions. Despite this, their effects are often neglected in num…
Smoothed Particle Hydrodynamics in pkdgrav3 for Shock Physics Simulations. I. Hydrodynamics
Thomas Meier, Douglas Potter, Christian Reinhardt +1
We present pkdgrav3, a high-performance, fully parallel tree-SPH code designed for large-scale hydrodynamic simulations including self-gravity. Building upon the long development h…
Terrestrial planet formation in the era of GPU computing
Simon L. Grimm, Joachim G. Stadel
In this chapter, we summarize the underlying numerical methods needed for efficient -body integration of planetary systems. We discuss how symplectic integrators have been devel…
Recent advances in modelling of global-scale collisions using smoothed particle hydrodynamics
Christian Reinhardt, Sabina D. Raducan, Thomas Meier +3
Impacts play a fundamental role in shaping the physical and chemical properties of the objects in our Solar System. Given the challenges in replicating such collisions through labo…
The possibility of a giant impact on Venus
Mirco Bussmann, Christian Reinhardt, Cedric Gillmann +4
Giant impacts were common in the early evolution of the Solar System, and it is possible that Venus also experienced an impact. A giant impact on Venus could have affected its rota…
On the origin of Jupiter's fuzzy core: constraints from N-body, impact and evolution simulations
Thomas Meier, Christian Reinhardt, Sho Shibata +3
It has been suggested that Jupiter's fuzzy core could be a result of a giant impact. Here, we investigate the expected impact conditions from N-body simulations. We then use state-…
