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 SolidWorks

Simulation-Led Design Using SolidWorks® and COMSOL Multiphysics®
- 3. Moderator Presenter Evan Yares Lorant Olasz Design World COMSOL
- 5. Agenda • Introduc8on – Simula8on‐led design • Interfacing CAD – What to think in preparing CAD for analysis? • LiveLink™ for SolidWorks® – Demonstra8on • Q&A
- 6. 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
- 7. 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
- 12. The Big Picture CAD Mul'physics Simula'on • Design products • Geometry and materials • Emphasis on specifica8ons for fabricated prototypes • Simulate behavior • Geometry, materials, discre8zed physics • Emphasis on analysis of virtual prototypes • Verify & op8mize the design Interface required
- 16. Merge Components
- 18. 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
- 21. Remove Holes
- 22. Remove Groove
- 23. 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
- 24. Poll Ques8on 2 • Do you prefer to simplify and defeature geometry in – SolidWorks – COMSOL Mul8physics – Other
- 25. COMSOL Mul8physics® • Mul8physics – Everything can link to everything • Adaptable – you can model just about anything • Usable – The right tool for the job
- 28. 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
- 30. Automa8c Parametric Sweep • Physics segngs retained in COMSOL model • Automa8c mesh • Automa8c solve • Automa8c result plots COMSOL Mul8physics Updated geometry Parameters SolidWorks ac8ve CAD file
- 31. Parameter Update • Update, in both SolidWorks® assemblies and parts, parameters that are – User defined, or – Model generated • Interac8vely link parameters in SolidWorks® to COMSOL COMSOL Mul8physics Geometry Parameters Top level SolidWorks assembly file Part 1 Sub‐assembly 1 Part 1 Part 2 Part 2
- 33. 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
