Geometry cleanup and Meshing
Aim:
To geometry clean and mesh the given three components as per the quality criteria.
Methodology:
- Create a mid surface for the component.
- Clean up the unnecessary lines and points on the mid surface.
- Mesh the component as per the quality criteria without any failed elements.
- Assign thickness for the mesh component as the original component.
Procedure:
- Considering the component in Fig 1 check for any kind of imperfections of the component and fix them so that there may be no surface deformation while creating mid surface.
Fig 1: part 1
2. Create a mid surface using the auto mid option in the mid surface menu. The mid surface of the component will be as shown below.
Fig 2: Created mid surface
3. Clean up the geometry for unnecessary lines and points as per the quality criteria. Toggle the unnecessary lines so that the lines can be toggled back when required.
4. After the cleanup process, start meshing the component as per the quality criteria given.
Traget length = 5mm
Minimum length = 3.5mm
Maximum length = 7mm
5. Failed elements will occur while meshing the components. Fix the failed elements using the quality index tools such as node place, element optimize, node optimize, drag tria elements etc.,
6. The meshed component will be as shown below.
Fig 3: before meshing Fig 4: after meshing
7. Thickness is to be assigned after meshing the component. Measure the thickness of the component, create a property card and mention the measured thickness. Assign the property card to the component card. To view the thickness of the component set the view mode to 2D detailed element representation. The thickness assigned component will be as shown below.
Fig 5: thickness assigned component
8. Similarly follow the above steps for the remaining two components. The meshed components are as shown below.
Fig 6: given component. Fig 7: Meshed component
Fig 8: given component. fig 9: meshed component.
Result:
Thus mid surfacing, cleaning up the geometry,meshing and assigning the thickness is completed as per the mentioned quality criteria.
