Assignment 1-2D Meshing Challenge
PART 1
Geometry Cleanup
- Trim unused surface. To fix this problem, using trim with surface (geom -> surface edit -> trim with surface/plane). Select horizontal surface for the first surface and vertical surface for the second surface.

- Delete unused surface using (delete -> surface -> select unused surface).

- For free edge (red line), to fix this problem use toggle edge (geom -> quick edit -> toggle edge -> select edge). After this tool is used the free edge will equivalence to another edge.

- Yellow line means that the line associate with 3 or more surfaces. For fixing this problem, delete surface that is inside the yellow line (delete -> surface -> select the surface).

Extract Midsurface
To extract midsurface used midsurface tool (geom -> midsurface -> auto midsurface -> select surface).

After
Ignore hole less than 5 mm in diameter
To remove holes with a diameter of less than 5 mm, a defeature tool is used (geom ->defeature -> pinholes).

After
Mesh
Making the mesh using automesh with a density of 3.5 mm. This density value gives a better mesh result than the density with a larger value. To get good mesh results, quality indexes such as smooth and drag tria element are used

PART 2
Geometry Cleanup
Some lines can be distrubting during midsurfacing process. To fix this problem, the point position should be moved to other point. 1 point should maintain the position and another point should be moving. This tool is located in geom -> quick edit -> replace point -> select points

Extract Midsurface
To extract midsurface used midsurface tool (geom -> midsurface -> auto midsurface -> select surface).

Geometry Editing
This feature is used to make the component easy to mesh. There are many lines and points that can be hidden from geometry. Unused line can be hidden using toogle edge (geom -> quick edit -> select line) and for unused point can be hidden using remove point (geom -> quick edit -> select point).

Mesh
Automatic mesh is used to mesh the goemetry, density for mesh is 5 mm. to get a good mesh quality use tool in quality index (ex. Smooth, place node, element optimize, drag tria element, etc).
