Explicit reversible integrator
WebAug 9, 2013 · When implicit time integration was used, simulation parameters were exactly as those in a real experiment, while in explicit time integration mass scaling was applied to reduce computation time. Two different mass scaling factors were used - 10000 (model Explicit 1) and 100 (model Explicit 2). Computation times (in minutes) for implicit and ...
