Description

Base class for processing boundary condition enforcing (BCE) particle forces in an FSI system.

This class handles the Fluid-Solid Interaction by enforcing i) forces from the fluid/granular dynamics system to the MBD system, and ii) displacement from the MBD system to the fluid dynamics system.

Constructor & Destructor Documentation

◆ ChBce()

chrono::fsi::ChBce::ChBce	(	std::shared_ptr< SphMarkerDataD >	otherSortedSphMarkersD,
		std::shared_ptr< ProximityDataD >	otherMarkersProximityD,
		std::shared_ptr< FsiGeneralData >	otherFsiGeneralData,
		std::shared_ptr< SimParams >	otherParamsH,
		std::shared_ptr< NumberOfObjects >	otherNumObjects
	)

Constructor of the ChBce class.

Parameters

otherSortedSphMarkersD	Holds the position, velocity, denisty, pressure, viscousity and types of the SPH particles.
otherMarkersProximityD	Holds the information for the neighbor search and mapping from the sorted variables to unsorted ones.
otherFsiGeneralData	Some general information, e.g, ordering of the phases.
otherParamsH	Parameter of the simulation.
otherNumObjects	Holds the number of sph particles on each phase.

Member Function Documentation

◆ Populate_FlexSPH_MeshPos_LRF()

void chrono::fsi::ChBce::Populate_FlexSPH_MeshPos_LRF	(	std::shared_ptr< SphMarkerDataD >	sphMarkersD,
		std::shared_ptr< FsiMeshDataD >	fsiMeshD
	)

Populates the BCE particles on the flexible bodies at the initial configuration of the system.

The local coordinates w.r.t to the coordinate system of the flexible bodies is saved and is used during the update stage. In such a condition the position and orientation of the body is enough to update the position of all the particles attached to it.

◆ Populate_RigidSPH_MeshPos_LRF()

void chrono::fsi::ChBce::Populate_RigidSPH_MeshPos_LRF	(	std::shared_ptr< SphMarkerDataD >	sphMarkersD,
		std::shared_ptr< FsiBodiesDataD >	fsiBodiesD
	)

Populates the BCE particles on the rigid bodies at the initial configuration of the system.

The local coordinates w.r.t to the coordinate system of the rigid bodies is saved and is used during the update stage. In such a condition the position and orientation of the body is enough to update the position of all the particles attached to it.
