MESHING OF THE HOOD ACCORDING TO THE GIVEN QUALITY CRITERIA

Objective : To mesh the hood part to the quality criteria.

 

Procedure :

• Import the given model into the graphic area of the hypermesh using import model option from the menu bar.

• First delete the solids. Then extract the Mid Surface separately for each component separately.
• Perform topology cleanup manually for each component and toggle the unnecessary lines.

• According to the given quality criteria in the mesh , the element size for the 2D mesh is 5.

For the meshing of the outer extract , half of the component is masked and meshed , after the meshing of unmasked half of component is done , then it is reflected to the other half of the component upon being unmasked. The tools used is  “reflect” under Tools from the main menu page.

For the meshing of the inner extract , half of the component is masked and the meshing of the unmasked part of the component is done , and then the elements of the  meshed section of the inner extract is reflected to the other side of the component. The tools used is  “reflect” under Tools from the main menu page.

• To attain the better quality of the mesh. Use quality index from the menu bar in the 2D menu page.

• In quality index there are many tools used to repair the mesh by reducing percentage trias percentage formed by meshing.

• Checking of elements is done by “ check elements” .

• In the “check elements” the numbers are set to the given quality criteria and checked by clicking on specific type of elements check. It indicates to the elements which are not meeting the quality criteria and those can be adjusted by using the necessary set of tools.

Result : The given model of the HOOD has been meshed according to the given quality criteria.
