Simula’on‐Led Design Using SolidWorks® and COMSOL Mul’physics®

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 SolidWorks

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

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? 

Page 15: Simulation-Led Design Using SolidWorks® and COMSOL Multiphysics®

Remove Components

Page 18: Simulation-Led Design Using SolidWorks® and COMSOL Multiphysics®

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

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
