Gerris Manual/Object hierarchy/GfsEvent

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 as follows:

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

with:


 * 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).
