Project 1 : CFD Meshing for Tesla Cyber Truck
AIM :- CFD Meshing for Tesla Cyber Truck
Objective :-
- To Identifying & cleanup all the topological errors in the given Tesla Cyber Truck Car model.
- To create a surface mesh.
- To Create a wind tunnel around Tesla Cyber Truck Car .
- To create a volumetric mesh to perform an external flow CFD analysis simulation.
Importing CAD the model :-
- To import the CAD model we follow below steps,
Go to file -> open -> browse the location of the CAD model -> select it click on open.

CREATING WIND TUNNEL:
1. First, we need to create reference points to create wind tunnel surfaces.
2. Select relative under points in topo mode, create a point below the car taking one reference point and entering the correct values.
3. And calculating the wind tunnel dimensions appropriately, we can create the wind tunnel accurately.
4. The wind tunnel dimmensions are:
car model: 5906mm .................. (x)
Front surface distance(from reference point): 22000mm .................. (4x)
Back surface distance(from reference point): 42000mm .................. (6x)
Top surface distance(from reference point): 19000mm .................. (3x)
5. After creating the bottom surface use the curves for having the reference of cons, we can delete all the hot points and curves.
Surafce meshing of wind tunnel:
1. We need to apply surface meshing depending the mesh length near the car and regions far away from it.
2. Therefore we need to apply different mesh lengths at the bottom and top wind tunnel surfaces.
3. We need to use spacing option to have a mesh length varying from the small mesh length size to larger mesh length.
4. Surface meshing can be achieved by doing this accordingly.

Conclusions:
1. Cybertruck car model is topo-cleaned and surface meshed appropriately.
2. Finally wind tunnel is created and surface meshed with reference to the car model size
