N-body simulations using customised potential-density pair basis sets | | M. J. W. Brown

2 Jun 1998 | | Subject: | astro-ph | | Abstract: | Potential-density pair basis sets can be used for highly efficient N-body simulation codes, but they suffer from a lack of versatility, i.e. a basis set has to be constructed for each different class of stellar system. We present numerical techniques for generating a biorthonormal potential-density pair basis set which has a general specified pair as its lowest order member. We go on to demonstrate how the set can be used to construct N-body equilibria, which we then evolve using an N-body code which calculates forces using the basis set. | | Source: | arXiv, astro-ph/9806031 | | Services: | Forum | Review | PDF | Favorites | |
