Abstract: |
In this paper, we implement a divergence cleaning method into Godunov
smoothed particle magnetohydrodynamics (GSPM).
In the GSPM, to describe MHD shocks accurately,
a Riemann solver is applied to the SPH method instead of artificial viscosity and resistivity
that have been used in previous works.
We confirmed that the divergence cleaning method reduces divergence errors significantly.
The performance of the method is demonstrated in the numerical simulations
of a strongly magnetized gas and bipolar outflow from the first core. |
