This model simulates the acoustics inside a sedan and includes sound sources at typical loudspeaker locations. Results show the total acoustic pressure field and the frequency response at points inside the cabin.

LiveLink™ for Inventor®

Perform COMSOL Multiphysics® Simulations from within the Autodesk® Inventor® Environment

LiveLink™ for Inventor® allows you to combine your COMSOL Multiphysics® analysis with a leading CAD software for 3D mechanical design – Autodesk® Inventor®. It allows you to integrate it with the capabilities of COMSOL Multiphysics from within the Inventor® modeling environment, and utilize its power for geometry design. Using LiveLink™ for Inventor®, you can integrate simulation with your design workflow. It includes features for repairing and defeaturing your geometries prior to simulation, making changes to your designs during the simulation process, and optimizing your designs through automated parametric sweeps or optimization studies.

COMSOL Desktop® Embedded Within the Inventor® GUI

COMSOL Multiphysics and LiveLink™ for Inventor® enable you to understand how a process or physical phenomenon operates in the environment for which your designs are targeted, and to simulate how different physics interact with each other in your design. Since LiveLink™ for Inventor® includes the COMSOL Desktop® as an embedded tool within the Inventor graphical user interface (GUI), switching between the two environments is seamless. Known as the One Window interface, this environment contains the Model Builder, Settings Windows, and tools, icons, and menu items that you are familiar with when modeling in COMSOL Multiphysics. It also allows you to investigate your results using Inventor’s graphic tools and rendering.

Product Features

  • A LiveLink™ interface that synchronizes between the Inventor® 2016 or 2017 versions of the CAD software and COMSOL Multiphysics® when both are running simultaneously
  • Works with an embedded COMSOL Desktop® within the Inventor® GUI, or as two separately run programs running simultaneously
  • Synchronize 3D geometric objects (solids and surfaces) between Inventor® geometries and COMSOL Multiphysics®
  • The synchronized geometry is associative, i.e., the CAD model can be modified in Inventor® without the need to re-apply model settings in COMSOL Multiphysics® after re-synchronization
  • Synchronize material selections and other user-defined selections between the Inventor® design and the COMSOL® model
  • Synchronize parameters between the Inventor® design and COMSOL Multiphysics® model to modify the COMSOL Multiphysics® geometry, either manually or as controlled by a parametric or optimization solver
  • File import of the most popular CAD file formats, see table below
  • Encapsulate geometries to model phenomena in the surrounding domains
  • Export geometry files to the Parasolid® and ACIS® file formats
  • Geometry repair through identification of geometric inconsistencies and knitting surfaces to create solids
  • Connect to COMSOL Server™ from within Inventor® to browse and run apps from within the Inventor® interface, including those that use geometry synchronized with Inventor®.
  • Defeaturing through the finding and deletion of fillets, short edges, sliver faces, small faces, and spikes
  • Manually deleting faces and healing the resulting gaps through filling (creating a new face) or patching (shrinking or expanding adjacent faces)
  • Detaching faces from a solid object to create a new solid object
  • Cap holes or empty spaces to fill the space and create modeling domains
  • Patch removed faces by growing or shrinking the surrounding surfaces to cover the removed face


This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Inventor via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.
