    Generic time loop

    The run() function below implements a generic time loop which executes events until termination.

    The timestep dt can be accessed as a global variable.

    double dt = 1.;

#include "utils.h"

trace
void run (void)
{
  iter = 0, t = 0., dt = 1.;
  init_grid (N);

  perf.nc = perf.tnc = 0;
  perf.gt = timer_start();
  while (events (true)) {

    We store the total number of cells advanced in time for computing speed statistics.

        update_perf();
    iter = inext, t = tnext;
  }

    Time/speed statistics are written out on standard output.

      timer_print (perf.gt, iter, perf.tnc);

  free_grid();
}

    By default we display the boundaries of the domain.

    event defaults (i = 0) {
  display ("box();");
}

    At the end of the run we need to empty the default display, otherwise we would append multiple copies when re-running.

    event cleanup (t = end, last) {
  display ("", true);
}
