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

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
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
