Parallel processing techniques for FE analysis: System solution

A sub‐structure based parallel solution of coupled thermo‐hydro‐mechanical modelling of unsaturated soil

“…The unknowns j 1 j 1Y 2Y F F F ns are solved on the host processor then passed to the each sub-processor where the unknowns j 2 will be recovered. Such an approach has been adopted previously, for structural/stress analysis problems and reported in the literature (Zois, 1988;Yagawa and Shioya, 1993;Saxena and Perucchio, 1993). As stated previously the work presented in this paper extends this approach to cover the more complex, transient nonlinear problem under consideration here and in particular develops a substructure based parallel solution for coupled thermo-hydromechanical problems in unsaturated soil.…”

Implicit micro–macro methods

“…When choosing Q x (y, 0) and Q y (0) to be random variables such that Q 2 (0) = 1 and Q x (y, 0)Q y (0) = 0 (for instance independent, normal distributions with zero mean and unit variance), then (20) leads to Q 2 y (t) = 1 for any time. Consequently (18) and (19) yield…”

“…As a consequence, the calculation of A Mm A −1 mm A mM proceeds in a "field-by-field" fashion reminiscent of the element-by-element approach [19]. In addition, both in (11A) and (11B), system size reduction is ideally suited to parallel hardware architecture [20].…”
