Member Function Documentation
◆ Initialize()
|
virtual |
Initialize the fluid system using initial states of solid FSI objects.
A call to this function marks completion of the fluid system construction. The boolean has_node_directions indicates whether or not mesh states also contain node directions.
Reimplemented in chrono::fsi::sph::ChFsiFluidSystemSPH.
◆ LoadSolidStates()
|
pure virtual |
Load FSI body and mesh node states from the given vectors.
The functions LoadSolidStates and StoreSolidForces allow using a generic FSI interface. However, a concrete fluid system can be paired with a corresponding FSI interface, both of which work on the same data structures; in that case, the custom FSI interface need not use the mechanism provided by LoadSolidStates and StoreSolidForces (which incur the cost of additional data copies).
◆ OnDoStepDynamics()
|
pure virtual |
Function to integrate the FSI fluid system in time.
Derived classes are responsible for updating the simulation time (m_time).
◆ StoreSolidForces()
|
pure virtual |
Store the body and mesh node forces to the given vectors.
The functions LoadSolidStates and StoreSolidForces allow using a generic FSI interface. However, a concrete fluid system can be paired with a corresponding FSI interface, both of which work on the same data structures; in that case, the custom FSI interface need not use the mechanism provided by LoadSolidStates and StoreSolidForces (which incur the cost of additional data copies).
