To Accelerate Your Solid Edge® Designs Through Simulation

Evaluate the Real-World Performance of Your Solid Edge® CAD Designs
LiveLink™for Solid Edge® is part of a robust platform that enables you to integrate multiphysics simulation into your 3D product design workflow. Solid Edge® is a 3D design system that can enhance your designs and make the design process more efficient. Combining Solid Edge 3D designs with the simulation capabilities in COMSOL Multiphysics allows you to visualize and optimize both the physical design and how it performs in the actual operating environment. A COMSOL model created from your design can include any relevant physical effects and their interactions ensuring that simulations are accurate.
COMSOL Multiphysics with LiveLink™for Solid Edge® maximizes productivity with tools and features that facilitate integration and expand the possibilities for design evaluation. Capabilities include optimization studies and automated parametric sweeps, techniques for geometry refinement, and concurrent updates to your designs during the simulation process.
COMSOL model geometries are directly synchronized with the corresponding CAD designs by using the functionality provided in LiveLink™for Solid Edge®. The geometry synchronization is associative, which means that physics definitions are preserved on model domains and boundaries throughout the design update process. Bidirectional updates are automatic when both programs are open at the same time and you are solving an optimization study or running a parametric sweep. During this process the CAD model parameters defined within Solid Edge are repeatedly accessed and modified by COMSOL Multiphysics based on either the evaluations of the optimization criteria or the parameter values specified for the sweep. Optimization studies make it easy to verify design parameters such as the placement of critical features, a task that would otherwise require setting up many simulations based on tracking multiple CAD files.
File Import and Export
LiveLink™for Solid Edge® also provides the file handling capabilities available in the CAD Import Module, including options for file import, and export. Both imported and synchronized CAD designs are handled in COMSOL Multiphysics using the Parasolid® geometry kernel that permits downstream modifications to the geometry, including Boolean geometry operations and partitioning to create additional domains for simulation, for example for fluid flow applications.
File import capabilities offer complementing functionality to the concurrent use of Solid Edge and COMSOL Multiphysics for geometry synchronization. COMSOL model geometries can be created by importing a CAD design from a range of platforms and file formats. 3D CAD file formats that are supported for import into COMSOL Multiphysics include the widely supported IGES, ACIS®, Parasolid®, and STEP, in addition to the Inventor®, SOLIDWORKS®, PTC® Creo® Parametric™, and PTC® Pro/ENGINEER® formats. Support for the CATIA®V5 file format is also available as a separate add-on module. The LiveLink™ products provide support for file export in the ACIS and Parasolid formats so you can readily share your updated designs with your colleagues.
Geometry Refinement for Precise and Efficient Simulations
When you first import a CAD file into COMSOL Multiphysics, any anomalies in the geometrical description of the design are automatically detected and corrected by the repair functionality. CAD designs also often contain many small geometrical features that are either part of the design or are inadvertently introduced during the design process. While small fillets are important for the fabrication of a part, they can ultimately make simulations less efficient and not necessarily contribute to the accuracy of the results. LiveLink™for Solid Edge® includes tools to refine your COMSOL model geometry prior to simulation so that you can choose which details to include for simulation. Geometry defeaturing capabilities are provided with LiveLink™for Solid Edge® that can automatically identify slivers, small edges, faces, or fillets. You can then decide whether to remove these features in Solid Edge or in COMSOL Multiphysics.
Another method you can use to prepare your CAD designs for simulation is to create a virtual geometry. Virtual geometry operations in COMSOL Multiphysics enable you to select specific features in a COMSOL model geometry that you do not want to include in your simulation studies. This technique does not modify the geometry, just hides the selected details before meshing, and it is an excellent way to exclude fine geometry details that typically require complex meshes and long computation times. An added benefit of this method is that the surface curvature of your design is preserved resulting in simulations with even greater precision when needed.

LiveLink™for Solid Edge®
A LiveLink™ interface that synchronizes between the Solid Edge® ST6 or ST7 versions of the CAD software and COMSOL Multiphysics® when both are running simultaneously
Synchronize 3D geometric objects (solids and surfaces) between Solid Edge® geometries and COMSOL Multiphysics®
The synchronized geometry is associative, i.e., the CAD model can be modified in Solid Edge® without the need to re-apply model settings in COMSOL Multiphysics® after re-synchronization
For faster synchronization of large assemblies, the associativity feature for faces, edges, or vertices can be turned off, if not needed
Synchronize parameters between the Solid Edge® 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
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
Supported File Formats
Note that not all file formats are supported on all operative systems, for details see System Requirements
COMSOL's LiveLink™ for Solid Edge® is the ultimate modeling software for Solid Edge® users. The partnership with Siemens PLM Software allows for CAD design synchronization, geometry repair and defeaturing, and parameter optimization. These features, combined with the COMSOL Multiphysics simulation capabilities, provide the complete modeling and simulation package.
