Modifying Imported CAD Geometry with the Deformed Geometry Interface

Step 1: Import the CAD File

• Supported Formats:– ACIS®– Catia® V5– Creo™ Parametric– IGES– Inventor®– Parasolid® – Pro/ENGINEER®– SolidWorks®– STEP– GDS/NETEX-G– ODB++

Step 2: Partition the Geometry

• Add a geometry object to subdivide the imported CAD• Partition, to create additional volumes

One objectThree domains

Step 3: Add Deformed Geometry Interface and define the deformations of the domains

At one end, apply displacements of: ( 0,0,0 )At the other: ( dLength, 0, 0 )In the middle domain: (dLength*(Xg/1[cm]),0,0)

Use a Global Parameter called dLength to control the extension of the domains

In the central region (which is 1cm long) use the Geometry Coordinates (Xg,Yg,Zg) to define the deformation based upon the coordinates of the original CAD geometry

Step 4: Use a swept mesh in the domain which will be stretched

This gives us greater control over the eventual shape of the elements in the deformed domain

Step 5: Use the parametric solver to sweep over a range of values
