Project 1-Meshing of Rear Wheel Holder challenge

PROJECT REPORT

AIM:

Check and correct geometrical errors on the Rear wheel holder geometry of a car and take mid surface,

assign the thickness then mesh it based on the element Quality criteria given below,

OBJECTIVES:

 To check and correct geometrical errors on the Rear wheel holder geometry of a car.

 Generating Mid surface and geometry clean-up on the given component

 Generating mesh on the given component with low tria concentration and proper mesh

flow and assigning the thickness.

BODY OF THE CONTENT:

The model given is the Hood model with a thickness of 0.75.

This is the CAD MODEL,

Deleted unwanted lines and solids. [Delete—select the solids and lines]

Generated the mid surface of the component using the command midsurface.

Used the Toggle subpanel to toggle edges for proper connection between surfaces.

Deleted unwanted Surfaces. [Delete—select the surfaces]

Searched pinholes and deleted with given diameter [Geometry—Defeature—Pinholes]

Used Washer split option to create washer on holes. [Quick Edit (F11) --Washer split]

Assigned the quality criteria of elements in check Elements 2D.

Meshed the components with element size 5 by selecting surfaces.

For proper mesh flow and changing tia to quads, mesh the elements and adjust the number of nodes.

For removing rotational quads, use the slip quads and drag elements.

Used Auto element cleanup to clean the element for accruing quality criteria.

Assigned the thickness by creating new property and material.

Assigned property to midsurface component.

Completed the meshing with proper mesh flow and low tria concentration.

CONCLUSION:

For the given Hood model, the mid surface after checking the geometrical errors, meshed with the

mid surface low tria concentration, and proper mesh flow with the given element Quality criteria.
