List of values that are computed and displayed every timestep.

Enumerator
INDEX	Current number of time step, indexed from 0.
RUN_TIME	Current time of the simulation in code units. Does not necessarily have to be 0 when run starts.
WALLCLOCK_TIME	Current wallclock duration of the simulation.
RELATIVE_PROGRESS	Progress of the run, always 0 <= progress <= 1, where 0 is the start of the run and 1 is the end of the run.
ETA	Estimated wallclock time to the end of the simulation.
TIMESTEP_VALUE	Current value of timestep.
TIMESTEP_ELAPSED	Wallclock time spend on computing last timestep.
PARTICLE_COUNT	Total number of particles in the run.
NEIGHBOUR_COUNT	Number of neighbours (min, max, mean)
SPH_EVAL_TIME	Wallclock duration of evaluation of SPH derivatives.
GRAVITY_BUILD_TIME	Wallclock duration of gravity tree building.
GRAVITY_NODE_COUNT	Number of nodes in used gravity tree.
GRAVITY_NODES_EXACT	Number of tree nodes evaluated by pair-wise interacting.
GRAVITY_NODES_APPROX	Number of tree nodes evaluated using multipole approximation.
GRAVITY_EVAL_TIME	Wallclock duration of gravity evaluation.
COLLISION_EVAL_TIME	Wallclock duration of collision evaluation.
POSTPROCESS_EVAL_TIME	Wallclock spent on data dump, particle visualization, etc.
TOTAL_COLLISION_COUNT	Number of collisions in the timestep.
MERGER_COUNT	Number of mergers in the timestep.
BOUNCE_COUNT	Number of bounce collisions.
BREAKUP_COUNT	Number of fragmentation collisions.
OVERLAP_COUNT	Number of particle overlaps detected during collision evaluation.
AGGREGATE_COUNT	Number of aggregates in the simulation (single particles are not counted as aggregates).
FRAME_ANGLE	Current angular position of the non-inertial frame.
SOLVER_SUMMATION_ITERATIONS	Number of iterations used to compute density and smoothing length in summation solver.
TIMESTEP_CRITERION	Criterion that currently limits the timestep.
LIMITING_QUANTITY	Quantity that currently limits the timestep.
LIMITING_PARTICLE_IDX	Index of particle that currently limits the timestep.
LIMITING_VALUE	Quantity value of particle that currently limits the timestep.
LIMITING_DERIVATIVE	Derivative value of particle that currently limits the timestep.
