Project 1 - 2D meshing on the instrumental Panel
Aim: 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.

- Given CAD model of the instrumental Panel and topo operation is performed.
- Then the model is checked for geometrical using the checks manager for a given geometry.
Here in the Checks window, all problems are reported with red color.
Under the Description column, the kind of problem is explained.
Focus functions are available in order to isolate geometrical problems and handle them easier. Select to fix all or specific reported problems by pressing
the right mouse button on the header of the list or one or more highlighted problems
- Errors Fixed.
- Give length parameters of 4 for both parameter and micros, and check the quality of the given CAD model of the instrumental panel.
- Use Manual approach to take Mid surface by offset command.
- set pid for the component.
Then the mesh parameters and quality criteria are assigned
Cons and Hot points are altered according to fit the criteria, i.e., for hemming surface cons are joined to avoid failing
minimum shell length using cut and join of macros tab.
Perimeter and macros are set for 5mm using the length in the perimeter option of the mesh tab.
Each Face(macro) of each component is meshed using the Best option in the Mesh Generation.
Mesh Quality is improved using reconstruct option in Shell mesh.
Further failed elements and tris are removed using Split, Swap, Join (Elements Tab), Smooth (Shell mesh tab), Paste
(Grids) and Num +/- (perimeter tab).
Performed manual topology cleanup, mid-surface extraction, and 2D meshing of the given model.
mesh the component satisfying Quality Criteria with better mesh flow.
Successfully meshed the component based on input quality criteria.
Results:
1. Performed geometry clean-up.
2. Performed mixed meshing with all elements passing the quality criteria.
