LiveLink™ for PTC® Creo®Parametric

Create and Associate COMSOL Multiphysics Models with PTC® Creo® Parametric™ Designs

LiveLink™ for PTC® Creo® Parametric™ is an add-on to COMSOL Multiphysics that seamlessly links 3D designs in the PTC® Creo® Parametric™ CAD system to COMSOL Multiphysics model geometries for simulation. Creo Parametric is an industry standard for 3D CAD and includes a comprehensive set of tools for maximum flexibility and productivity. COMSOL Multiphysics with LiveLink™ for PTC® Creo® Parametric™ enables you to benefit from the advanced capabilities in Creo Parametric to produce state-of-the-art designs and then integrate them into a COMSOL Multiphysics model for analysis and optimization.

LiveLink™ for PTC® Creo® Parametric™ updates your design workflow to include multiphysics simulation capabilities that allow you to better understand how your product or design performs in the intended operating environment. Models in COMSOL Multiphysics can include essentially any relevant physical effects and their interactions to accurately simulate your design. LiveLink™ for PTC® Creo® Parametric™ includes features to prepare CAD geometries for simulation and to update designs during the simulation process for use with automated parametric sweeps or optimization studies.

Update a Design and Preserve the Physics

LiveLink™ for PTC® Creo® Parametric™ synchronizes your designs in Creo Parametric with your COMSOL Multiphysics models and automatically propagates design updates while running the programs concurrently. CAD models do not have to be manually exported or imported into COMSOL Multiphysics with each change. Parameters, including part dimensions or placement, defined in Creo Parametric can be iteratively accessed from COMSOL Multiphysics enabling simulations with parametric sweeps and optimization studies. Through direct synchronization, LiveLink™ for PTC® Creo® Parametric™ retains the associated physics definitions on model domains and boundaries even when features are updated or added to a design.

Product Features

  • A LiveLink™ interface that synchronizes between the PTC® Creo® Parametric™ 2.0 or 3.0 versions of the CAD software and COMSOL Multiphysics® when both are running simultaneously
  • Synchronize 3D geometric objects (solids and surfaces) between PTC® Creo® Parametric™ geometries and COMSOL Multiphysics®
  • The synchronized geometry is associative, i.e., the CAD model can be modified in PTC®Creo® Parametric™ without the need to re-apply model settings in COMSOL Multiphysics® after re-synchronization
  • Synchronize parameters between the PTC®Creo® Parametric™ design and COMSOL Multiphysics® model to modify the COMSOL Multiphysics® geometry, either manually or as controlled by a parametric or optimization solver
  • Automatically generate selections on the synchronized geometry in the COMSOL®model from the material assignments in the PTC® Creo® Parametric™ file.
  • Connect to COMSOL Server™ from within PTC® Creo® Parametric™ to browse and run apps together with PTC® Creo® Parametric™, including those that use geometry synchronized with PTC® Creo® Parametric™.
  • 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
  • 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 Creo Parametric via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.
