Description

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

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

Inherits chrono::fsi::ChFsiGeneral.

	)

Constructor of the ChBce.

Parameters

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

◆ Populate_FlexSPH_MeshPos_LRF()

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

virtual

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

The local coordinates w.r.t to the coordinate system of the rigid body 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 markers attached to it.

◆ Populate_RigidSPH_MeshPos_LRF()

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

virtual

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