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 >.
