Detailed Description

Limits step increase to a constant ratio.

Member Function Documentation

◆ can_be_delayed()

bool StepChoosers::LimitIncrease::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::LimitIncrease::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 >.
