Tool Test 1
Model one
Objective: Extracting MId surface for both models and apply mesh with quality criteria.
1. Forgiven the model one opening model and check for geometry errors.
Click on the file and open model file 1. Then open presentation parameters and reduce detail on demand. Then checking for geometry errors And removing errors
using a combination of 'UNIVERSAL DELETE, TOPO, RELEASE, AND PASTE. Then running the geometry check tool for any topology error.
2. MID SURFACE EXTRACTION OF MODEL 1 AND SETTING PID's
a. After geometry check extracting mid of door trim using manual method. first, need to check the thickness at different places using a measuring tool for better
mid-surface extraction. Then using 'inot, not, and, or just to make certain parts of model visible for better visibility of model. Then extraction of the mid surface using
a set of commands like 'middle and offset'. And using the topo command to join two cons. After extracting mid for all components and run the geometry check tool for
any errors.
Offset command is used to create a face at some distance from the original face
The Middle command is used to create a middle face between two selected faces. for better mid-surface extraction using middle make sure both faces have the same
b. Taking mid surface of ribs and fixers and joining then to the main mid surface. using commands like extend, and create a new surface. After that check for geometry check for any type of errors.
3. GENERATING MESH WITHIN QUALITY CRITERIA
a. Generating mesh on door trim model's component one by one using 'BEST' option from mesh generation. But first set the perimeters or element size as '4mm' Select the whole model and press the middle mouse button to confirm. To apply mesh select "best" then select the component and middle mouse button to confirm mesh, and also checking for good mesh flow. For good mesh flow, there should not be two trias pointing in the same direction. To remove the trias using swap, split command, and pasting nodes.
b. To remove the off elements using commands 'CUT, JOIN, SPILT, MOV SURFACE, paste nodes, DELETE HOT POINTS, SWAP, RECONSTRUCT MESH, smooth
mesh, each command, and creating removable cons to eliminate off elements.
DACH COMMAND: Dach command is used to remove fillet or create mid cons.
CUT COMMAND: Cut command is used to remove double cons or to remove unwanted coons which creating off elements.
SPLIT AND SWAP COMMAND: Split command is used to split the quad element into tria element which can create tria using nodes or edges of the element. and
swap command removes the edge and paste to the adjacent edge.
MV SURFACE: Move surface is used where a minor change in the placement of nodes of elements can eliminate off elements.
RECONSTRUCT MESH: Reconstruct mesh is used to create mesh on meshed surfaces.
PASTE: Paste command is used to paste two nodes and remove tria element.
SMOOTH: Smooth command is used after correcting some mesh flow, to smooth the mesh throughout the selected area of surface.
Model two
Objective: Extracting MId surface for both models and apply mesh with quality criteria.
1. Forgiven the model two opening model and check for geometry errors.

CONCLUSION:
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.
