simulation-led design using solidworks® and comsol multiphysics®
DESCRIPTION
Multiphysics has earned the reputation as an excellent approach for simulation in engineering and science. Applying multiphysics simulation early in the product development process brings you reliable computer models to verify and optimize your designs This webinar will demonstrate how the COMSOL LiveLink for SolidWorks bridges the gap between design and analysis, integrating real-world simulation right into the CAD design environment of SolidWorks. Attend this webinar to learn: The importance of multiphysics modeling for true simulation of real-world applications How to integrate analysis into the design process the workflow of modeling with COMSOL Multiphysics and SolidWorksTRANSCRIPT

Agenda
• Introduc8on – Simula8on‐led design
• Interfacing CAD – What to think in preparing CAD for analysis?
• LiveLink™ for SolidWorks® – Demonstra8on
• Q&A
Simplify with Physics in Mind
• Re‐evaluate assump8ons and approxima8ons based on results – Symmetry – Fillets
Heat transfer: Plot of temperature
Structural Mechanics: Plot of von Mises stress
Simplify in SolidWorks
• Suitable for designs with complex topology
• Use when history of the CAD design is available • Changes of the CAD design may cause rebuild errors,
which are 8me‐consuming to deal with
• Requires knowledge of SolidWorks
Poll Ques8on 1
• What so.ware are you currently using? – COMSOL Mul8physics® and LiveLink™for SolidWorks®
– COMSOL only – SolidWorks only
– Other
Concep8on
• Understanding the physics
Concep8on Design Tes8ng Process planning Produc8on
Design
• Improving prototypes

The Big Picture
CAD • Design products • Geometry and materials
• Emphasis on specifica8ons for fabricated prototypes
Mul'physics Simula'on • Simulate behavior • Geometry, materials,
discre8zed physics
• Emphasis on analysis of virtual prototypes
• Verify & op8mize the design
Interface required
Interfacing CAD
Preparing Your CAD Design for Analysis
Assess
• What is the scope of the model?
• Which level of detail is necessary? • Can you remove components? • Can you merge components with similar material proper8es?
• Can you make use of symmetry?
Remove Components
Merge Components
Iden8fy Symmetry Planes, Split Geometry
Simplify the Components
• Are there small details that can be removed? – Details that are approximately 10‐4 8mes smaller than the size of the
object can o.en be regarded as small
– Look for fillets, small faces, sliver faces, short edges
• Are there larger details that can be removed? – Look for fillets, holes, or other features not needed for the analysis – Keep the physics in mind – You can include removed details later
Remove Sliver Face
Remove Small Fillets
Remove Holes
Remove Groove
Simplify in COMSOL Mul8physics
• Specially suited to remove small details (~10‐4)
• Defeaturing opera8ons saved in the COMSOL model for subsequent edi8ng
• No knowledge of CAD so.ware required
Poll Ques8on 2
• Do you prefer to simplify and defeature geometry in – SolidWorks
– COMSOL Mul8physics – Other
COMSOL Mul8physics®
• Mul8physics – Everything can link
to everything
• Adaptable – you can model just
about anything
• Usable – The right tool
for the job
• CAD interoperability and geometry modeling
• Physics and materials • Meshing
• Solving • Visualiza8on • Postprocessing • Export/Import of data
All Inclusive Environment
LiveLink™ for SolidWorks®
CAD and Simula8on
• Set up your COMSOL model only once for mul8ple CAD design configura8ons
• Op8mize the CAD design by automa8cally sweeping over, and solving the model, for a range of design varia8ons
• No need to keep track of several CAD files with varia8ons of the same design
• Transferred geometry can be defeatured and modified in COMSOL
• Leverage COMSOL’s capability of server and cluster compu8ng • Integrate with LiveLink™ for MATLAB® for even greater
flexibility
A bidirec8onal Interface
• Transfer parameters to CAD program
• Transfer geometry to COMSOL

Geometry Parameters
COMSOL Mul8physics • Update, in both SolidWorks® assemblies and parts, parameters that are – User defined, or – Model generated
• Interac8vely link parameters in SolidWorks® to COMSOL
One Window Interface
• Available with LiveLink™ for SolidWorks®
• Create mul8physics models inside the SolidWorks user interface
Modeling with the One Window Interface
• Changes to the SolidWorks® geometry are automa8cally detected, and synchronized to the COMSOL model
• Dimensions linked to the COMSOL model are automa8cally transferred
• Easily create a package of the COMSOL model and SolidWorks® file for sharing
