Project 1 : CFD Meshing for Tesla Cyber Truck

Aim:-CFD Meshing for Tesla Cyber Truck

Project :-

Import the Model And its delete the half part by plane cut method.

Check The Geometrical Error  single cones and resolve it.

Solvesingle cones.

Create PID as shown in the picture.

Assign PID in model 

Select the PID 

1. Target lengths for the different parts of a model are as follow:
2. Body - 3 mm , Minimum Length -1mm , Maximum Length -5mm
3. Lights - 4 mm, Minimum Length -2 mm , Maximum Length -6mm
4. Rims and Tyres - 2 ,Minimum Length -0.2mm , Maximum Length -3mm
5. Rear Light - 4 mm , Minimum Length -2 mm , Maximum Length -6mm
6. Window - 4 mm,Minimum Length -2mm , Maximum Length -6mm 

Rear Light Off Elements is zero

In Tyre we found min distance is 0.2 then for Quality Check Parameters we should take the 0.2 minimum length is 0.2mm.

 

Off elements is zero tyre mesh.

Symmetry the half model.and check geometry error.

check the off elements .its  find zero.

Meshing complete.

WInd Tunnel Create

creates the points in front side and rear and top surface the creat the curves then create surfaces 

Measure the length of the car is 5960 mm. its the value of X

 Create the Point as per the following

Front Face -4X+X1(it is the distace centre point to  front face)

Rear Side -6X+X2(it is the distace centre point to  Rear face)

Top Face -3X+X3(it is the distace centre point to  Top face)

Right Face - X

Left Face-X

Create the points. steps Section Pont →Relative →middle click →define distance acording to the direction.

Create lines through curve 

Curve Section → Create →click Start point & End Point  centre click →ok

Shoud must on the curve Tool

Create Face & Create PID & Assign PID.

after create the wind tunnle face delete the points .

Target Length of wind Tunnle

Bottom Face -80mm

Top Fce-400 mm

Front & Rear Face Spacing 1.1 mm

Off elements is zero in result.

 Conclusion :

• The imported CAD model of Tesla cyber truck is Topologically Cleaned & Corrected all the feasible surface errors to perform external aerodynamic analysis.
• Surface mesh is generated with the required element size.
• Reconstructed the mesh as per the mesh quality required at Corners & at Intersection of edges.
• Worked with the errors occured in the Mesh.
• Created a wind tunnel For external aerodynamic analysis.
