Constructor & Destructor Documentation

◆ ~INSHierarchyIntegrator()

IBAMR::INSHierarchyIntegrator::~INSHierarchyIntegrator ( )

The destructor for class INSHierarchyIntegrator unregisters the integrator object with the restart manager when the object is so registered.

	)

protected

The constructor for class INSHierarchyIntegrator sets some default values, reads in configuration information from input and restart databases, and registers the integrator object with the restart manager when requested.

This constructor sets the default coarsen and refine operator types to:

"CONSERVATIVE_COARSEN" and "CONSERVATIVE_LINEAR_REFINE" for U
"CONSERVATIVE_COARSEN" and "LINEAR_REFINE" for P
"CONSERVATIVE_COARSEN" and "CONSERVATIVE_LINEAR_REFINE" for F
"CONSERVATIVE_COARSEN" and "CONSTANT_REFINE" for Q

The other constructor allows these default values to be overridden.
