The Hybrid Module gives you the state-of-the-art in vibro-acoustic analysis methods.

Developed as part of a long term research program by ESI, in conjunction with leading academic institutions and industrial consortia, this module enables you to create fully coupled FE/BEM/SEA models in a single analysis. The ultimate in modeling flexibility; use the right combination of subsystems to accurately model the response of your product across the entire frequency spectrum.

Benefits

• Create efficient system level models of noise and vibration across the full frequency spectrum (including the difficult mid-frequency range)
  
• Extend your existing SEA models to mid and low frequencies by adding
  local FE subsystems to describe complex junctions and stiff components
  
• Refine the dominant transmission paths in your models with the use of FE subsystems (optimize junction designs to minimize structure-borne
  transmission, optimize local constructions for minimum input power)
  
• Extend your existing FE/BEM models to higher frequencies (remove
  computational expense and capture the physics of a problem by modeling high modal density subsystems statistically with SEA)
  
• Quickly add SEA acoustics, poroelastic materials and random acoustic loads to existing FE models (perform TL, radiation efficiency and diffuse acoustic loading predictions in a fraction of the time it takes to perform a full FE/BEM/IEM calculation)

Features

• Hybrid point, line and area junctions between FE structure and SEA subsystems/loads (include isolators and poroelastic treatments)
  
• Fully coupled models and full implementation of the Hybrid FE/SEA method
