• Quickly analyse the frequency behaviour of trims, with results equivalent to a Kundt's tube set-up.
  
• Compare the noise reduction potential of different trims before running an analysis on the full model.
  
• Design composite trims to reach a targeted noise reduction in each frequency range
  

• Better handle cases like underwater acoustics, medical imaging, or acoustic wave propagation in turbomachinery where nonlinear phenomena are very likely to occur.
  
• Get more accurate noise levels and frequency spectrum predictions more quickly (tests show 30% to 60% reductions in the runtime compared to previous versions).
  
• Assess the validity of linear acoustic assumptions in use cases where nonlinear effects are likely to occur.
  

• Get the right parameters for an accurate simulation on the first attempt.
  
• Save time during model set-up.
  
• Launch simulations without requiring a deep knowledge of adaptative meshing technology.
  

• Automatically check and visualise the mapping between a CFD mesh and an acoustic mesh.
  
• Avoid launching expensive aeroacoustics runs where acoustic sources are not well accounted for.
  
• Get robust aeroacoustic data recovery.
  

• Get a 3D view of the full model and its subsystem definition.
  
• Define the connections between the SEA subsystems more quickly.
  
• Better assess the energy transfer between subsystems and check plausibility.
  

• Colour selections for materials: ActranVI can now automatically assign colours or visibility states (opacity, wire mesh) to each material. These will be applied to all components that refer to those materials, allowing better model visibility based on materials. Clicking on a material will also highlight the parts of the model made of this material.
  
• Support for arbitrary cross sections in iTM: In addition to the canonical shapes (circular, annular and rectangular), iTM can now extract CFD data and apply it to the acoustic mode characteristics of any arbitrary shape. An acoustic modal extraction is done first on the given cross-section and the mode amplitude and phases are computed for the CFD based on those. Please note that arbitrary sections are only available with the SPPV method.
  
• Virtual SEA performance improvements: By automatically aligning the PID configuration of the model meshes with the subsystems, fewer matrices are computed and stored, leading to significant disk-usage gains (above 90%) and runtime gains (30 to 60%). As those matrices are computed based on bigger domains (subsystems), this can also increase the peak RAM consumption of the models (from 50 to 100%). If that is an issue, you can deactivate this by specifying DO_NOT_MERGE_PIDS 1 in the analysis parameters.
  
• Load case management: To ease pre- and post-processing of multi-load case Actran analysis, a "tag" mechanism has been implemented. Each load case has a unique set of tags (examples: boundary condition name, amplitude, radial order, user-defined tags, etc.). Those tags will then be carried over during the computation and present in the output files, allowing much easier load case identification during post-processing.
