Challenge

Week 12:Project 2-Meshing of Rear Wheel Holder challenge

Objective:

To mesh the rear wheel holder panel using the given quality criteria.

CAD model:

Procedure:

By using offset command mid surfaces were capture. As the floor panel thickness is 0.75 mm mid surfaces was generated in middle for 0.325 mm offset from skin.

Surfaces were cleaned up using tools under geometry cleanup and manual surfaces cleaning tools.

All open patches and open points were closed. And surfaces/ edges which were failing for min element size were isolated or modified to capture proper mesh.

Some bead which was failing for elements size were removed as its impact was not critical.

Surfaces were examined for checking symmetricity and split as per observation.
After complete geometry surfaces were updated for mesh. A mesh with base element size of 5 mm was generated manually for each surface.

While generating mesh main objective was to respect feature lines in most possible condition.
For some places were element me failing element cleanup were done. Due to which some elements were disturbed from feature line. But Mesh QI was achieved with no Elements failed.
After completing the symmetric mesh, it was cleaned for all fail elements and were reflected to other side and checked for feature lines captured or not.

Create property card and assign thickness

While correcting mesh it was taken care for capturing feature lines properly to improve post processing accuracy.
The holes and fillets were achieved properly.
Simultaneously, The Free edges and open nodes were checked and corrected properly.
While performing this task I mainly focused on capturing the features properly in mesh. Tried to eliminate maximum Tria-element without compromising with the Feature lines.
Mesh was checked for the normal and elements which were in reverse were corrected.

FINAL MODEL:

The model is meshed with given quality criteria.
