This section shows videos of the simulation of complex flexible multibody systems with fluid structure interaction, component mode synthesis and contact.
These simulations can be performed with the open source version of HOTINT, while it is not possible yet to set up these examples in script language.
Description: This video demonstrates the coupled simulation of rigid and flexible bodies with a fluid. The robot including the control, the plate, the jar and the vessel have been simulated in HOTINT and the fluid in LIGGGHTS. These two simulation programs, HOTINT and LIGGGHTS, have been coupled via TCP/IP.
Description: run up of a piston-engine. The 3 parts are described with GCMS-elements. Dynamic simulation.
