Week 12:Project-1-Meshing of Door Inner Panel Challenge

Aim

To perform midsurface operation and mesh the side door

Objective

To perform offset of the complex areas like ribs, circular areas

Maintain mesh flow

capture feature line and geometry

Maintain Quality criteria

Quality Criteria set for meshing

Mid surface extracted for Side door

some of the surfaces were closed using spline and shortcuts like

F12 - Automesh

F10- 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 and alter the length by changing value

F2 - Delete

Shift +F7 - Project line or point were used.

Surface edit, line edit panel was used panel was used

In Tool organize tool was used.

In F11 shortcut Toggle edge, surf split replace point project point tools were used

Ribs were projected to the surface using project to surface tool

After Geometry Cleanup and Clearing all surfaces capturing geometry Midsurface

Side door body mesh

Ribs Separarated to apply Property

Ribs can offsetted

and in some areas the ribs can created by creating a line and by selecting nodes by path and use Shift +F7 shortcut to project surface from parent geometry

Edges were found to be inline

To Apply Properties Go to -> Preferences -> User Profiles Select radioss

give thickness

and assign the property to ribs and other componenets

Use Visualization tool to check 2D Element Detailed Representation

Conclusion

• Proper Geometry needs to be captured during midsurface
• Capture feature line during extracting midsurface or offsetting to be checked
• Property Geometry cleanup for better mesh flow
• Avoid trias in edges and arround critical areas
• Analysis results are based on mesh, mesh flow to be maintained throughout the component
• Check mesh with feature line and midsurface geometry
• Maintain Quality criteria
• Check quality criteria after completion of each split and rectify to save time.
