Week 6- Challenge

Aim

To perform meshing on given hood model using Hyperworks

Objective

• To generate midsurface and cleanup geometry
• To generate 2D mesh according to given Quality criteria
• To generate mesh in away it passes all Quality criteria
• To reduce trias concentration possible ways

Procedure

1. Import the given cad file to be meshed

2. Delete solids

After deletion of solids create mid surface and geometry cleanup

Creation of Mid Surface and Manual Geometry Cleanup

Latch Mid Surface and manual geometry cleanup

All the element size were found within given Quality criteria

Hinge Mid Surface and Geometry cleanup

Outer Extract Mid Surface and Geometry cleanup

Inner Extract Mid surface and Geometry Cleanup

Tools used for Mid Surface and Geometry Cleanup

Midsurface generation tools

Geometry Cleanup tools

Quality Criteria Setup

Latch Meshed

All the element size were found within given Quality criteria

Hinge Meshed

Outer Extract Meshed

Inner Extract Meshed

Tools used to

Quality Index

Hyperworks tools used to perform geometry cleanup and maintain element Quality

Shortcuts like ;

F12 - Automesh

F11- Check elements panel

F3- Node Equivalence

F7- Align nodes/Node Operation

F6 - Combine or Split elements

Shift+F12 - Smooth

F4 - Distance between two nodes or points

F2 - Delete

Shift +F7 - Project line or point

Defeature command in Geometry was used to toggle edges at a time

Quik edit tool was used to for geometry clean up and after mesh operations

During the entire process tria elements were optimized

F10 - Check Mesh quality

Element Size was given as 5mm

The mesh was adjusted to obtain uniformity by using replace nodes or points tool and other tools

Final meshed Hood model
