Function Documentation

makeEnginePartitioningTrigger()

std::unique_ptr< Trigger< gridfire::solver::PointSolverTimestepContext > > gridfire::trigger::solver::CVODE::makeEnginePartitioningTrigger

(

const config::TriggerConfig &

cfg

)

Compose a trigger suitable for deciding engine re-partitioning during CVODE solves.

Policy (as of implementation):

• OR of the following three conditions: 1) Every 1000th firing of SimulationTimeTrigger(simulationTimeInterval) 2) OffDiagonalTrigger(offDiagonalThreshold) 3) Every 10th firing of TimestepCollapseTrigger(timestepGrowthThreshold, timestepGrowthRelative, timestepGrowthWindowSize)

See engine_partitioning_trigger.cpp for construction details using OrTrigger and EveryNthTrigger from trigger_logical.h.

Returns

A unique_ptr to a composed Trigger<TimestepContext> implementing the policy above.

Note

The exact policy is subject to change; this function centralizes that decision.
