Week 12:Project 2-Meshing of Rear Wheel Holder challenge
Aim
To perform geometry cleanup, extract midsurface of Rear wheel Holder and mesh the component
Objective
To capture parent geometry features when capturing midsurface
To maintain mesh flow and quality criteria
Given Model
In ->Tool using Organize tool all the components were made into one by moving
Midsurface and Geometry Cleanup
due to minimum element failure criteria buttons surface was deleted and surface was filled using filler surf in F11
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
Quick edit panel - F11 was used to split surfaces, Toggling edges and geometry cleanup
After Geometry Cleanup and Clearing all surfaces capturing geometry Midsurface
Circular areas were captured by using Quad elements
Central area has curvature and the mesh flow is aligned
Rear Wheel Holder Mesh
Quality Index, elem cleanup and rebuild mesh tools were used to reduce trias concentration and maintain mesh flow
Quality Criteria
Check Elements - Shortcut F10
Minimum Length Criteria
Maximum Length Criteria
Warpage Criteria
Edges were found to be inline
Feature lines were captured throughout the mesh
Assigning Thickness
Use Visualization tool to check 2D Element Detailed Representation
Final Image of Meshed Model
Conclusion
- Proper Geometry needs to be captured during midsurface
- Capture feature line during extracting midsurface or offsetting to be checked
- Proper Geometry cleanup required 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.
