3d meshing of the housing component

AIM:

To 3d mesh the given component according to the following criteria

Elements sizes: Min- 2mm, Target- 5mm,Max- 7mm

Tet collapse: 0.15

THEORY:

Generally, 3d meshing is performed whenever the thickness of the components goes beyond 6mm or below 1/20 thickness area ratio. Few examples are like turbochargers, engine parts, intake manifolds, tyres, etc.3d meshing is generally done in two ways Tetra meshing and Hexa meshing. Generally, tetra meshing is preferred than Hexa meshing abiding to the complexities of Hexa meshing. In analysis perspective, 3d Hexa mesh will give better results than tetra mesh due to its better shape function

Our main aim while performing 3d tetra meshing is to maintain the tet-collapse which is distance from the opposite face divided by the area and multiplied by 1.24

PROCEDURE:

1. We first import our required geometry. We have 2 components the housing and the hub part
2. We make hub and the housing in different collectors for easiness in meshing
3. We perform the necessary geometry clean up for the component
4. We 2d mesh it first only with trias
5. We then covert it to tetra mesh using the tetra mesh option in the 3d panel
6. We then check for tet collapse and correct it with the help of tetra remesh option setting up the required parameters in tetra mesh parameters
7. The models are tetra meshed and tet-collapse is maintained

MODEL:

RESULTS:

• The components were 3d meshed according to the given criteria
• Features were captured properly
