Q. Du et P. Gray, Numerical algorithms of the Lawrence-Doniach model for layered superconductors and their parallel implementation, SIAM J SC C, 20(6), 1999, pp. 2122-2139
The Lawrence-Doniach model is often used for studying vortex dynamics in su
perconductors which exhibit a layered structure. In solving these model equ
ations numerically, the added degrees of complexity due to the coupling and
nonlinearity of the model often warrant the extensive use of high-performa
nce computers for their solution. Approaches for reducing the complexity of
the Lawrence-Doniach model and for simplifying the calculation of the nume
rical solution are presented in this work. Numerical results and benchmarks
are included for models involving the motion of vortices due to an applied
current and the pinning of vortices due to nonuniform pinning sites (norma
l inclusions) placed within the material.
