◆ AddWaves() [1/2]

void chrono::fsi::tdpf::ChFsiFluidSystemTDPF::AddWaves ( const IrregularWaveParams & params )

Add irregular wave conditions.

Note that the number of bodies is overwritten during initialization.

◆ AddWaves() [2/2]

void chrono::fsi::tdpf::ChFsiFluidSystemTDPF::AddWaves ( const RegularWaveParams & params )

Add regular wave conditions.

Note that the number of bodies is overwritten during initialization.

◆ LoadSolidStates()

void chrono::fsi::tdpf::ChFsiFluidSystemTDPF::LoadSolidStates ( const std::vector< FsiBodyState > & body_states )

overridevirtual

Load the given body and mesh node states in the TDPF data manager structures.

This function converts FEA mesh states from the provided AOS records to the SOA layout used by the TDPF data manager. LoadSolidStates is always called once during initialization. If the TDPF fluid solver is paired with the generic FSI interface, LoadSolidStates is also called from ChFsiInterfaceGeneric::ExchangeSolidStates at each co-simulation data exchange. If using a custom TDPF FSI interface, MBS states are copied directly...

Implements chrono::fsi::ChFsiFluidSystem.

◆ StoreSolidForces()

void chrono::fsi::tdpf::ChFsiFluidSystemTDPF::StoreSolidForces ( std::vector< FsiBodyForce > & body_forces )

overridevirtual

Store the body and mesh node forces from the TDPF data manager to the given vectors.

If the TDPF fluid solver is paired with the generic FSI interface, StoreSolidForces is called from ChFsiInterfaceGeneric::ExchangeSolidForces at each co-simulation data exchange. If using a custom TDPF FSI interface, MBS forces are copied directly...
