Project 2 - 2D meshing on the instrumental Panel
For the given component, check for the geometrical errors and mesh with the given element Quality criteria. After meshing the component the thickness has to be assigned.
Write a detailed report on your meshing process and also mention which method you used to extract the mid-surface along with the reason.

- Procedure
Step 1: Open the IP model using file > open , and give an initial Topo operation for the entire component to paste the perimeters together so that the all the single cons we see while opening the model will become double cons.
To do this go to Topo Module > Faces > Topo, select the entire component with left mouse box selection and give a middle mouse confirmation.
In order to refine the perimeter of the model go to Mesh module > Perimeters > Length, select the entire model with left mouse box selection and confirm the selection with middle mouse click. Input the length value as 1 or 2 mm in the box and hit enter.
Step 2 : Geometry check-up
Now we have to check for geometrical errors and perform geometry clean up
Go to Tools > Checks > Geometry > Execute
Step 3: Extract mid-surface
After fixing all geometrical errors and clean-up the geometry now we have to extract the mid-surface.
Since IP substrate is a plastic component it has varying thickness so we opt for Faces > Offset option and Faces > Middle option to extract mid-surface instead of Faces > skin option or automatic mid-surface option.
The main body of IP has a uniform thickness of 0.6 mm, so we use Topo Module > Faces > Offset option to extract the mid-surface.
Step 4: Meshing the mid-surface with given element quality criteria
Before meshing we have to defeature the areas where it's failing for minimum length in element quality criteria.
Input the element quality criteria and Mesh parameters
