SHD Sim Explicit
Explicit fluid-structure interaction
Coupled inside the explicit solver
OpenRadioss
In development.
This module is phase 5 — a market decision more than a technical one. The solver behind it is chosen and its capability is known. SHD Sim is available today.
What it is
Fluid and structure coupled inside the explicit solver rather than between two codes, which is what fast events demand: there is no time to exchange and iterate between solvers when the whole event lasts milliseconds. Suits fluids behaving more like a load than like a flow field.
What this analysis needs from you
- A fluid representation inside the explicit solver, not a separate CFD run
- Equation-of-state data for the fluid
- The largest models in this module, and the longest runs
Typical uses
- Fuel tank sloshing and rupture in impact
- Hydrodynamic ram in filled structures
- Water landing and ditching
- Underwater explosion against a hull
Industries
Sectors where this analysis is routinely asked for.
- Automotive fuel systems
- Aerospace ditching
- Defence
- Marine
What comes out
- Coupled fluid-structure response
- Slosh impact pressures
- Structural loads from the surge
- Baffle effectiveness
Backend
OpenRadioss
Chosen for this analysis type, with its capability verified against the module plan — not decided later.
Status
Phase 5 — a market decision more than a technical one. Telling us you need this analysis moves it up the order — modules are sequenced by who is waiting for them.
