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
Concep8on Design Tes8ng Process planning Produc8on
Tes8ng
• Running virtual experiments

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
