Week 6-Meshing of Hood Challenge

Week 6 – Meshing of Hood Challenge

Objective: Mesh the Hood model with below mentioned Quality Criteria, mesh size = 5units, Mixed element.

CAD model image (.IGES File):

Figure: CAD model

Procedure with required images:

Step-1: Import the Step file. Generate mid-surface of each component separately.

Figure: Mid-surface extraction

Figure: Toggle all unwanted lines

Step-2: Define the quality criteria as shown below

Preferences-> criteria editor->apply

Figure: Tools->check elems

Save failed and click F5 to retrieve elements and mask them. Reverse the elements and find attached elements. Then 2D->Quality index and use smooth, element optimize, place node or other options to correct the issues.

Step-3: 2D->automesh->QI criteria-> choose crash 5 mm.

Figure: Setting Quality Criteria

Step-4: automesh-> mixed type 5mm mesh size.

Step-5: Check quality of elements

2D->quality index

Figure: element quality check

Step-6: Hinge reinforcement

Shift+F10 to check which elements are failing

2D-> Quality index-> element optimize

2D->smooth option

Figure: Hinge reinforcement mesh

Step-7:

Geometry->Quick edit-> Toggle edge

Tools->edges->find edges->delete edges-> preview equivalence.

Geom-> lines->midline

Geom-> surface edit-> Trim with lines

2D-> automesh

Results:

Check Quality index of each component.
