Abstract: |
We present the results of comparisons between the SPH code SEREN
and the AMR code MG for the thin shell
instability, Kelvin–Helmholtz instability and moving polytropes.
These show that there is good agreement for the thin shell instability
and moving polytropes, but SPH only give satisfactory results for
Kelvin–Helmholtz instabilities with a quintic kernel and artificial
thermal conduction. For problems without self-gravity, SEREN requires
approximately 20–50 times more computation time to achieve the same
accuracy as MG, even without the use of AMR. |
