Detailed Description

template<typename StepChooserUse>
class StepChoosers::Constant< StepChooserUse >

Suggests a constant step size.

bool StepChoosers::Constant< StepChooserUse >::uses_local_data ( ) const

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_magnitude passed to the call operator is not considered local data.

Implements StepChooser< StepChooserUse >.
