Week 6-Meshing of Hood Challenge

Aim :

       To mesh the hood component with given quality criteria by using Hyperworks software.

Objective :

       The main goal is to create midsurface of the given component and to mesh the component using hypermesh.

Procedure :

Choose the profile as optistruct and import the given component.

To create midsurface for the component to apply mesh.

Before doing midsurface the geometry has to be cleaned manually by using the options available in quick edit menu.

Then the meshing is to done by using the automesh menu and the element size is for 5 units and we choose mixed elements for meshing.

The meshing process is done using splitting the surface and meshing the adjacent surface.

The main thing is the elements should not fail for the given quality criteria and the number of trias are to be reduced.

With the help of parent geometry we assign the thickness property to the components.

In this project there are four components to be meshed and the size variance will be from small to large components.

By working on the different size components we learn to explore many menu and options in the software.

We use reflect option if the component has symmetrical surface.

When working on the surface we opt topology revision to disassociate and while working on the elements we opt to remesh option.

We can also check for duplicates in the elements and connectivity errors in the elements

We use edge menu to check for equivalence and to find the edges.

We use mask menu to mask the failed element and we solve it.

To view the component with thickness we use 2D detailed element representation option.

The quality index menu will help in many ways in swap, drag, split, node optimize or element optimize.

The meshed components with quality criteria attached below for reference.

Reference pictures of the components :

Latch component,

Hinge component,

Outer extract of hood component,

Inner extract of hood component.

Result :

       In the process of learning and working on different tools in the software the meshing of components is done successfully with satisfying the given quality criteria.

       The components are meshed and satisfied the given quality criteria successfully by exploring many menu and options by using Hyperworks software.
