1. Import the given Component using the Import option in Hypermesh.

                       

                                                 Fig: Imported Parallel Bracket Model

     2. Creating a Mid-surface of the given component by using Geom-midsurface option.

     3. After creating a Mid surface of the given component, Use Washer Split option and create a washer as 5mm on each pinhole.

                             

                                                           Fig: Midsurface Component

     4. After Creating a Mid surface, Go to 2D-automesh option and set element size and mesh the component.

     5. While meshing, Keep the number of elements on both sides of the part as equal to avoid tria & quad elements.
