A tensorial approach to computational continuum mechanics using object-oriented techniquesIn 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 and ... ...

A fast serial algorithm for the finite temperature quenched Potts modelAn 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 ... ...

A new algorithm for computation of SU3 Clebsch–Gordon coefficientsA 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 convention... ...
