Description

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

This class handles the Fluid-Solid Interaction by enforcing:

forces from the fluid/granular dynamics system to the MBD system
displacements from the MBD system to the fluid dynamics system

◆ Populate_RigidSPH_MeshPos_LRF()

void chrono::fsi::sph::BceManager::Populate_RigidSPH_MeshPos_LRF ( std::vector< int > fsiBodyBceNum )

Populate the BCE markers 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.
