◆ ExchangeSolidForces()
|
pure virtual |
Exchange solid phase force information between the multibody and fluid systems.
- Extract fluid forces on rigid bodies from fluid system and apply them as external loads to the MBS.
- Extract fluid forces on mesh nodes from fluid system and apply them as external loads to the MBS.
Implemented in chrono::fsi::ChFsiInterfaceSPH.
◆ ExchangeSolidStates()
|
pure virtual |
Exchange solid phase state information between the MBS and fluid system.
- Extract FSI body states from MBS and apply them to the fluid system.
- Extract FSI mesh node states from MBS and apply them to the fluid system.
Implemented in chrono::fsi::ChFsiInterfaceSPH.
◆ GetFsiBodyForce()
| const ChVector3d & chrono::fsi::ChFsiInterface::GetFsiBodyForce | ( | size_t | i | ) | const |
Return the FSI applied force on the body with specified index.
The force is applied at the body COM and is expressed in the absolute frame.
◆ GetFsiBodyTorque()
| const ChVector3d & chrono::fsi::ChFsiInterface::GetFsiBodyTorque | ( | size_t | i | ) | const |
Return the FSI applied torque on the body with specified index.
The torque is expressed in the absolute frame.
