Acoustic Analysis
Pre-post for large-scale acoustic analysis


Utilized by automotive and electric appliance manufacturers
we can model faithfully to the shape your noise reduction requirements in a short time with various functions.
Jupiter-Acoustic has made it possible to perform a series of flow from acoustic model creation to result processing with a simple operation without a dedicated Pre / Post .
We can also propose the suitable tools for various problems that will satisfy both beginners and advanced users so as to improve the performance of their products.

Target users

For beginners ● Easy modeling and analysis settings
For advanced users ● Supports ultra-large-scale models
● High-precision, high-efficiency modeling
● Supports various analysis types according to the purpose
● 3D plot display such as waterfall
● Abundant sound energy flow display

Case study

  • Company T Example
    Modeling man-hours reduced to 1/3
  • Company N Example
    Modeling man-hours reduced to 1/16


Jupiter-Pre system for structural analysis with abundant mesh editing functions for high-precision model creation.
It supports large meshes, so it maintains high performance even on engine models.
Jupiter-Post also has a cross-section display function that is convenient for checking the sound pressure distribution in the acoustic space.

Tie trap
It is possible to create a detailed wrap mesh that retains the structural model shape.
Minimum ellipsoid / convex hull creation command
It is possible to automatically create the minimum ellipsoid and convex hull for the infinite boundary surface.

It is possible to display an animation of sound pressure contour without stress.
It also has a cross-section display function with a high degree of freedom.
Post processing required for analysis such as contribution map and panel contribution are also possible from the results of element contribution.

Operation flow

Structure-Shaping acoustic boundaries
Filling holes in CAD or finite element models and joining parts
Boundary surface remesh
Creating an acoustic area
Creating a sound absorbing layer by meshing in the acoustic area
Extraction of the outer surface of the structural model
