Week 4 - 2D Meshing for Sheet Metal

OBJECTIVE: For the given CCB CAD model, perform Geometry cleanup & mid surface extraction & Mesh it with the below 2D element Quality criteria.

PROCEDURE:

* Initially after importing the iges file, perform topo operation and ensure the model is properly stitched.

* After that perform perimeters length and assign distance between nodes and surfaces to desired length. Here in our model it is 5mm.

* Perform geometry cleanup and fix all the issues using auto fix and manually if required

* Perform mid surface extraction. Here i used two methods to extract mid surface, i.e mid surface skin & offset method.

*I used different property id's for different thicknesses for easy access.

*Before meshing quality parameters are set up as mentioned in the question.

* Meshing is performed. I used Reconstruct, Free Mesh, Best Mesh, Swap, Spilt, Collapse while meshing.
