Aeroelastic and fluid-structure interactions

Enable fluid-structure interactions by coupling Simcenter Flightstream with external user-defined executables. The solver outputs aerodynamic loads at structural nodes, which are processed externally to compute displacements. These displacements are then reapplied to deform the surface grid for iterative aeroelastic analysis.

Hydrodynamic wave modeling and resistance

The Simcenter Flightstream marine free surface solver extends the core incompressible panel solver. Based on inviscid wave dynamics, it quickly and accurately generates surface wave patterns from submerged body motion and analyzes free surface effects. With minimal user input, it automatically creates a free surface mesh and couples it with the body solution.
