Meshing the Car Hood Model

OBJECTIVE:

• To check for geometrical errors.
• To mesh the given component as per the given quality criteria.
• To assign thickness after meshing.

QUALITY CRITERIA:

GIVEN COMPONENT:

Outer_Extract

Latch and Hinge reinforcement_extract

Inner_Extract

MID-SURFACE EXTRACTION:

The mid surface has been extracted using the auto Mid-Surface option.

Outer_Extract

Inner_Extract

Latch and Hinge reinforcement_extract

PROCEDURE:

• Check for the geometrical errors
• After the geometry cleanup, extract the mid surface using the midsurface option.
• Create locked views for the individual components.
• Edit the quality criteria and mesh parameters as per the requirements.
• Cleanup the mid surface for the meshing. Edit the cons and faces using cut, project cut, release, paste, orient and topo options to clean up the geometry for meshing.
• Mesh the components individually.
• Using the length option assign macros and perimeters points length as 5mm.
• Use the Number option or the Number +/- option to add or remove nodes.
• Use best and free options in the mesh generation to generate the mesh.
• Edit the quality and flow of the mesh elements using split elements, reconstruct, improve, smooth and fix quality options.
• Create property id to assign thickness to the elements.

QUALITY CRITERIA AND MESH PARAMETERS:

Inner_Extract

ASSIGNING THICKNESS AND PROPERTY ID:

CONCLUSION:

Geometry cleanup, mid surface extraction and meshing of the given component have been completed as per the given quality criteria and mesh parameters.

The tria-element percentage has been reduced to 3.31%.

Thickness is assigned on the mesh as per the thickness of the given geometry.
