A tensorial approach to computational continuum mechanics using object-oriented techniquesAIP Publishing - Tập 12 Số 6 - Trang 620-631 - 1998
Henry Weller, Gavin Tabor, Hrvoje Jasak, Christer Fureby
In this article the principles of the field operation and manipulation (FOAM)
C++ class library for continuum mechanics are outlined. Our intention is to make
it as easy as possible to develop reliable and efficient computational
continuum-mechanics codes: this is achieved by making the top-level syntax of
the code as close as possible to conventional mathematical notation for tensors

A new algorithm for computation of SU3 Clebsch–Gordon coefficientsAIP Publishing - Tập 8 Số 3 - Trang 355-359 - 1994
H. T. Williams, Colin J. Wynne
A new, operator-based algorithm for the calculation of Clebsch–Gordon
coefficients for the group SU3 is introduced, and an ansi c program for its
implementation is described. The algorithm involves the use of raising and
lowering operators in analogy to a standard pedagogical approach to the more
familiar SU2 Clebsch–Gordon coefficients. The nature of the approach makes the
sign conventions utiliz... hiện toàn bộ
A fast serial algorithm for the finite temperature quenched Potts modelAIP Publishing - Tập 7 Số 1 - Trang 97-107 - 1993
Gregory N. Hassold, Elizabeth A. Holm
An efficient serial algorithm for finite temperature, quenched Potts model
simulations of domain evolution has been developed. This ‘‘n-fold way’’
algorithm eliminates unsuccessful spin flip attempts a priori by flipping sites
with a frequency proportional to their site activity, defined as the sum of the
probability of success for every possible spin flip at that site. Finite
temperature efficien... hiện toàn bộ
