Week 12:Project-1-Meshing of Door Inner Panel Challenge

objective :

Meshing of the Inner panel of Side Door CAD Model with Target element Size of 4 units and with proper mesh flow and with tria concentration as well .
The Meshed Model should pass all the quality Criteria provided .
Assigning the proper Thickness to the meshing .

Quality Criteria :

CAD Model of inner panel of the side door :

Procedure :

Initially Cad Model is imported and some Manual Geometrical clean up done .
Using Surface Tool and the Quick Edits Tool from Geom Tool , geometrical cleanup is done .
Whole Inner panel of side door is then devided into the 4 pieces and kept them in diierent collector for better meshing convineance .

In below image , marked surface height too short to make surface for geometry clean up ,using the Geom - Surface edit - Extend Tool , surface is extended and then using the Geom - surfaces - Ruled Tool surface is created which can be seen below .

Using the Geom - Defeature Tool , The Side Door inner panel is the Defeatured For the surfaces where mesh will fail for trhe minimum length element.
The surfaces which are hypermesh fail to defeature are defeatured manually .

Then for all the 4 peices of the side door inner panel , the Midsurfaces are extracted using the Geom - Midsurface Tool as .
Now here also the hypermesh is missed to extract midsurfaces of the some surfaces can be seen below .
This missed surfaces are Extracted manually using the Geom - Surface Edits - Offset Tool as ,

Here in below image . missed midsurface is Created toggling lines using the Quick Edits - toggle edges and the surface is generated using the Ruled - surfaces - geom Tool .

For Some surface the midsurfaces were not prperly created , which are also created manually using the geom - Surface Edits - Offset Tool as ,

The Area which haviung the more than 6mm thickness are captured draging the surface with the help of Node using the Geom - Surfaces - Drag Tool as ,

Now Meshing of the Side door inner panel is done step by step to get proper meshing and the proper mesh flow as well .
Initially the Quality criteria setting is done and view is converted into the By element Quality , so that we know which elements are failing every time we mesh the surface .
After meshing Every time we need to Preview Equivalence for every element to have proper connectivity between elements using the Tool - Edges - Element Tool the equivalnce can be checked .

Surfaces with improper attachements are tackled as follows .
Firstly surfaces with not proper attachments are deleted and then created the surfaces with hole as seen below .

After all meshing the whole component , I have assigned the midmesh thickness using the Mesh - Assign - Midmesh Thickness Tool .

Results:

Front side : Back side :

With Shaded Elements and the feature lines .
