| Zusammenfassung |
| Magnetohydrodynamic (MHD) codes achieved considerable success in modeling
space physics systems, such as the solar corona or the magnetosphere.
Unfortunately, fluid models cannot describe the magnetic reconnection
physics accurately, which plays an important role in determining
the dynamics of the whole system. Particle-in-cell (PIC) codes can model
the reconnection process accurately, but they are much more expensive than
fluid models. Coupling the global fluid code with a regional PIC code can
provide a physically accurate yet economic global model. Implicit PIC codes
are especially suitable to be coupled with fluid codes, as they can
employ much larger time steps and grid spacing than explicit PIC codes,
and allow the fluid and PIC discretizations to employ comparable
spatial and temporal resolutions. Adaptive mesh refinement in the
fluid code can also facilitate bridging the scales between the two codes.
We describe our initial progress towards coupling the adaptive mesh
based BATS-R-US MHD code and the implicit PIC code iPIC3D. |
