Project-2-Meshing of Door Inner Panel Challenge

PROJECT REPORT

AIM:

Check and correct geometrical errors on the Plastic geometry and take mid surface, assign the thickness then mesh it based on element Quality criteria given below,

OBJECTIVES:

• To check and correct geometrical errors on the geometry.
• 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 and assigning the thickness.

BODY OF THE CONTENT:

This is the CAD MODEL,

To make the work easier divided the component into 4. Trimmed with plane. [surface edit—trim with surf/plane]

Used mask option to isolate the components to be worked.

Removed the surface fillets [Geometry—Defeature—Surface fillets] by applying minimum and maximum angles.

Created the surfaces with the Drag surface command by selecting the line and length to be dragged.

Used the command replace to geometry clean up.

Used the Extent Tool for Surface Creation. [Surface edit—Extend]

Used the command Trim with surfaces and deleted unwanted surfaces by Delete command.

Created mid surface by creating the mid lines of top surface using Lines command as shown below.

The area which is having more than 6mm thickness, captured them like in the picture

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

Used the washer split command to proper mesh flow.

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.

Checked the element normals and dependency.

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

CONCLUSION:

For the given model, Took the mid surface after checking the geometrical errors, meshed with low tria concentration, and proper mesh flow with the given element Quality criteria. Assigned the thickness for each element.
