4 LiveLink Interface

5 Benefits Set up your COMSOL model only once for multiple CAD design configurations Optimize the CAD design by automatically sweeping over, and solving the model, for a range of design variations No need to keep track of several CAD files with variations of the same design Transferred geometry can be defeatured and modified in COMSOL Leverage COMSOL s capability of server and cluster computing Integrate with LiveLink for MATLAB for even greater flexibility

6 LiveLink for CAD: Supported Software New CAD Software and Version LiveLink for AutoCAD AutoCAD 2012, 2013 LiveLink for Creo Parametric Creo Parametric 1.0, 2.0 LiveLink for Inventor Inventor 2012, 2013 LiveLink for Pro/ENGINEER Pro/ENGINEER Wildfire 4.0, 5.0 Creo Elements/Pro 5.0 LiveLink for Solid Edge Solid Edge ST5 LiveLink for SolidWorks SolidWorks 2011, 2012 LiveLink for SpaceClaim SpaceClaim 2011+, 2012

7 A bidirectional Interface Transfer parameters to CAD program Transfer geometry to COMSOL COMSOL Multiphysics Updated geometry Parameters CAD program active CAD file

8 Automatic Parametric Sweep Physics settings retained in COMSOL model Automatic mesh Automatic solve Automatic result plots COMSOL Multiphysics Updated geometry Parameters CAD program active CAD file

9 Parameter Update Update, in both CAD assemblies and CAD parts, parameters that are COMSOL Multiphysics - User defined, or - Model generated Geometry Parameters Interactively link parameters in the CAD program to COMSOL* Top CAD assembly file Part 1 Sub-assembly 1 Part 1 Part 2 * Available with LiveLink for Creo Parametric, LiveLink for Inventor, LiveLink for Pro/ENGINEER, LiveLink for SolidWorks Part 2

10 One Window Interface Available with LiveLink for SolidWorks Create multiphysics models inside the SolidWorks user interface

12 File Import Import solids, surfaces, curves, and points - Form solids from surfaces Length unit from CAD file or from COMSOL geometry Automatic repair during import - Healing gaps, removing spikes, short edges, slivers, etc. Location and type of errors in geometry reported after import

13 Dedicated Geometry Kernel Integration of the Parasolid kernel, which is one of the leading 3D modeling kernels Used by default with a license for the CAD Import Module or a LiveLink for CAD Product Enables defeaturing and repair of imported CAD geometry Enables combining imported geometry with geometry generated in COMSOL

14 Geometry Sequence Click on a node in the Model Builder to access and modify the settings for the geometry operations Enable or disable geometry operations in the sequence Delete operations or insert new ones Fully parameterized geometries

15 Defeaturing and Repair

16 CAD Repair Perform after import of CAD files - Repair similar to the automatic repair during import - Knit to solid heals gaps to create closed surfaces or solids Heal gap and create solid

17 Defeaturing tools Interactively search for and remove - Fillets - Small faces - Sliver faces - Spikes - Short edges Delete Fillets

18 Delete Sliver Faces Remove face and extend other faces to fill gap

19 Delete Faces Select faces to be deleted Use to remove holes Use to remove larger features from the geometry Faces are deleted and the wound is healed by growing surrounding faces

20 Detach Faces Select faces to be detached into a new solid object Use to create a solid for fluid calculation in a channel or hole Use to create a domain to apply different materials Faces are detached into separate objects. New faces are created by growing surrounding faces.

21 Cap Faces Select edges to form new faces on solid or surface objects Use to create a domain for fluid calculation in a channel or hole Use to create a domain to apply different materials Use to close a surface object and create a solid

22 Virtual Geometry and Mesh Control Operations

23 Virtual Geometry Operations Complements defeaturing and repair operations Hides geometry features from the mesher Use to get rid of Sliver faces Short edges Small faces Undesired surface partitioning Small domains due to overlapping solids Difference from defeaturing Works on the finalized geometry that is seen by the mesher Keeps the underlying surface curvature

24 Mesh Control Operations Gain precise control over mesh layout and density in regions of known rapid changes or steep gradients, which may occur for example in CFD simulations Selected geometry features are available exclusively to control local mesh properties and do not affect the subdivision of edges, faces, or domains when applying physics settings Domain for mesh control in benchmark model of turbulent flow field around a car-like object
