Week 6-Meshing of Hood Challenge

Aim-

To do a 2D mesh of given Hood assembly as per given data and to do a quality check as per given condition mentioned below.

Element quality criteria :-

Procedure-

Intially we have to import the model given to us, for that go to import>>import model and then select file and click on import.
The given hood assembly consists of 4 parts, viz. 1.inner extract, 2. outer extract, 3.hinge reinforcement extract & 4. Latch reinforcement extract

Step 1:- Import Geometry :-

Step 2:-Delete solide from Geometry:-

Inner extract-

Make Sure that current selected component is inner extract only.
Now go to delete and remove all the solids present in the active model.
Go to topology view and check for any geomerty errors in the model.
Now go to mid surface and create mid surface.
Now again check for the geometry errors in the generated mid surface and do cleanup if required.
Now we can see in the below snap that the geometry is symetric from all side except the centre postion non highlighted.

Step 3:- Dimensioning:-

Step 4:- Mid Surface Creation:-

Step 5:- Meshing Of All Components:-

Step 6:- Creat Material And Proparty with the Thickness of 0.375mm :-

Conclusion-

We should first check the geometry errors and clear them manually, also we must toggle lines which are not required and which are very close to each other.
We must take care of lines & Edges by which we are going to create mesh.
We cannot ignore orremove trias at the curved edges and there should not be any back to back trias.
We should maintain mesh flow with trias and quads, by that we can only get a good mesh of any part.
