Project 1 : CFD Meshing for Tesla Cyber Truck
AIM:
•To check and solve all geometrical errors and Assign appropriate PIDs.
•To Perform meshing with the suitable Target length and element Quality criteria.
Target Length Used For Each Elements:
- Body= 3mm
- Lights= 4mm
- Tyres= 2mm
- Window = 2mm
Procedures and Results:
Geometric Clearence:
Step1:
Hitting TOPO to remove maximum Single Cone Error
1.Before using TOPO
2.After using TOPO
Step2:
Geometric checking of the model
Step3:
Using Plane Cut tool to cut the model symmetrically
A.
B.
C.
Step4:
Removing the red cone, triple cone and intersection error
A. Errors in Tyre Section
B. After Geometric correction
C. Error in front element
D. After Geometric clearence
E. Wireframe mode of Geometric Clearence
Sttep5:
Assigning the PIDs(Lights,Tyres,Body,Window)
Step6:
Assigning the quality criteria
Skewness =0.5
Min Length = 0.1
Max Length= 6
Step7:
Suface Meshing:
A.Setting up the Mesh parameters for Wndows and Tyres
Target Length= 2mm
B. Mesh Of Windows and Tyres
C.Setting up the Mesh parameters for Body
Target Length= 3mm
D. Mesh Of Body
E.Setting up the Mesh parameters for Light
Target Length= 4mm
F.Mesh Of Light
G.After Complete Mesh:
Step8:
Joining of other Half Element
Transform, Copy,Symmetry
Step9:
Complete Mesh Of The Model
Step10:
Creating the Wind Tunnel:
A.Taking The Relative Points:
B. Creating the Bottom Surface with the help of Relative Points:
C. Making the Faces of the Wind Tunnel:
D. Creating Top Face using Off set
E. Wind Tunnel
Step11:
Surface meshing of the Wind Tunnel
A. Bottom Face
Target Length= 50mm
B. Top Face
Target Length= 150mm
C. Complete Mesh Of the Wind Tunnel
(using grow mesh analysis on Side Fsce)
Conclusion:
•This model has not been attached with the necessary surface meshing and volume meshing criteria, criteria considered by own according to necessity.
•This challenge is exposed to the process of volume meshing and using elements such as Growing mesh Analysis.
•This challenge helped us to explore different methods of geometry cleanup.
•This challenge helped to deal with red cone errors, penetration errors, intersection errors and warnings.
This challenge helped us to explore different tools of ANSA, such as offset, planeCut, coons2curve, improve the shell mesh, using of grow mesh analysis
•This challenge helped us to learn about creating a wind Tunnel considering the measurements.
