GfsEvent

From Gerris

Events are used to control any action which needs to be performed at a given time during a simulation. This includes one-off actions as well as periodically repeated actions.

The syntax in parameter files is:

GfsEvent *NAME { start = 0.1 istart = 10 ( step = 1.2 | istep = 10 ) end = 0.4 iend = 123 }

with:

NAME

The (optional) name of the event. The name of the event has to be preceded by the * symbol.

start

Physical starting time (default is zero). The "end" keyword can be used to indicate the end of the simulation.

istart

Time step starting time (default is zero).

step

Repeat every step physical time units (default is infinity).

istep

Repeat every istep time steps (default is infinity).

end

Stop at or before this physical time (default is infinity).

iend

Stop at or before this number of time steps (default is infinity).

Note that the parameter block and the name of the event are optional.
