Detailed Description

Suggests step sizes to place steps at specific times.

The suggestion provided depends on the current time, so it should be applied immediately, rather than delayed several slabs.

Member Function Documentation

◆ can_be_delayed()

bool StepChoosers::StepToTimes::can_be_delayed ( ) const

overridevirtual

Whether the result can be applied with a delay.

StepChoosers setting the .end or .end_hard_limit fields of TimeStepRequest must return false here.

Implements StepChooser< StepChooserUse::Slab >.

◆ uses_local_data()

bool StepChoosers::StepToTimes::uses_local_data ( ) const

overridevirtual

Whether the result can differ on different elements, so requiring communication to synchronize the result across the domain. This is ignored for LTS step changing.

Note: As this is only used for slab-size changing, the last_step passed to the call operator is not considered local data.

Implements StepChooser< StepChooserUse::Slab >.
