Version 2024.2 – Update
▪ An improvement has been introduced to the FSI interface which provides increased stability of coupled simulations with strong fluid-structure interaction.▪ The functionality “Filling of hollow structures” offered in the FSI section has been improved to achieve an increased reliability and completeness of the filling process particularly when structural erosion occurs.▪ An erroneous check concerning […]
Co-Simulation Interface V3 for LS-DYNA
▪ Version 3 of the co-simulation interface for fluid-structure-interaction (FSI) has been implemented into the LS-DYNA user-subroutine dyn21.f/loadud. This interface permits the coupled simulation of explosively loaded structures with LS-DYNA and the APOLLO Blastsimulator V2024.2. ▪ LS-DYNA models can be used for a coupled LS-DYNA/APOLLO simulation without any formal modifications. The interface implemented in dyn21.f/loadud […]
What’s new in Version 2024.2
FSI Co-Simulation Interface▪ The co-simulation interface has been updated and is now available as version 3. This version offers an optional inclusion of the local fluid impedances to the data send from APOLLO to the coupled structural dynamics code. The impedances are optionally used for the pressure extrapolation when the structural solver performs sub-cycles. Thereby, […]
