Week 3 - 2D meshing for sheet metal

Motto : Learn and perform mesh & mid surface of Hood model with required Quality criteria.

Steps performed:

1. Studied Hood model (sheet metal part) had 5 parts which has different thickness. from that got idea of offset dimension.

2. Part wise individual PID assigned with material properties.

3. Performed geomentry clean up and check - with Topo option tools. (parametric Node defination, features captured, divided and deleted with sufaces cons)

3. Manual mid plane extraction done using Mid surface & offset - Faces.

4. Started Mesh generation with proper quality data assigned. ( Best Mesh, Remesh, reconstrct)

5. Opposite trias avoided using split and join.

6. Performed increase / decrease nodal numbers on perimeter segments.

7. Inner Fillets are captured & avoided in Outer panel’s bend region.

8. Ensured parts are met with minimal trias % & good mesh flow.

Conslusion:

Time taken for Hood model bit high due to initial learnings. understood regular practices and use of shortcut keys will minimize time and make efficency in FE mesh. will implement those learnings in week 4 challenges. overall good learnings thanks for the knowledge.
