Week 12:Project 2-Meshing of Rear Wheel Holder challenge

Aim :-

To generate mesh on the given rear wheel holder & assign thickness and material to the same.

Quality Criteria :-

Procedure :-

1. Import the given geometry to hypermesh.

Fig 1 :- Import CAD File

2. Check for open surfaces & geomerty to be cleaned.

Fig 2.1 :- Improper Geometry

Fig 2.2 :- Free Edges

3. Clean the geometry using Geometry->Quick Edit->Filler/Toggle/Split surf->OK.

Defeature the buttons shown in the below snap & toggle the circles using the above instructions.

Fig 3.2 :- Surface without Bottons

Fig 3.3 :- Clean Geometry

Fig 3.4 :- Wireframe View of Clean Geometry

4. Extract the midsurface of the geometry using Geometry->Midsurface->Auto midsurface->Select Surface->Extract.

Fig 4.2 :- Midsurface Extracted

5. Create parameter & Criteria file for batch meshing.

8. Create property & a material card as shown in the below snap.

The thickness of the given component is 0.75 units.

9. Assign the property & material to the model.

Final View :-

Result :-

2D meshing is created on the extracted mid surface of the given model, thickness and material are assigned to the model, mesh elements are free from quality issues.
