| Start from static equilibrium: solve K x = f (no inertia) once before the time loop, then set v = a = 0. Takes precedence over the initial-acceleration heuristic (calc_init_accel_), whose perturbation parameter 4e6/dt^2 degenerates to a near-static solve anyway when dt is large relative to the structural time scale, yielding a spurious a_init = pert*x_static instead of a physical acceleration. | |

◆ setStartTime()
|
inline |
Set the start time of the integration window.
By default the window (Initial Time, Final Time) is fixed at construction from the "Trapezoid Rule" parameter list. These setters let a driver – e.g. a coupling loop that advances the solver one outer step at a time – retarget the window to successive segments of global simulation time before each evalModel call, mirroring Piro::TempusSolver's setStartTime/setFinalTime. The model then sees true simulation time through InArgs::set_t (a time-dependent boundary condition, body force, or material lookup gets the correct time instead of the fixed window's). The internal time step delta_t = (Final - Initial) / Num Time Steps is recomputed; the dynamics depend only on delta_t, so shifting the window's origin leaves the integration unchanged.
The documentation for this class was generated from the following file:
