Project 1 : CFD Meshing for Tesla Cyber Truck

Objective: Check and resolve any geometry errors and assign appropriate PIDs to a specific Tesla Cybertruck model. Perform a mesh with appropriate target length and element quality criteria.

Steps:-

TOPOCLEANUP

PID determination

Create a 2D mesh with different mesh lengths for different PIDs

Create a wind tunnel

Volume meshing

Initial geometry:-

This is our raw geometry, if we activate single opposites, we will see the whole geometry covered with single opposites. To avoid doing single minuses for the entire geometry, this solves the single minuses problem.

Geometry after applying TOPO tool

All single cons are converetd to double cons

Geometry Check done

Geometry is ready to go for meshing

Creating a wind tunnel:

We're going to build a wind tunnel for the car.

For wind tunnels, measurements are:


Think of the car's length as X.
Maintain the wind tunnel 75 mm from the vehicle's bottom.
The length of the wind tunnel in front of the car should be 4X; the overall length of the tunnel is equal to half the length of the car plus 4X.
The length of the wind tunnel behind the car should be 6X, and the overall length of the tunnel from the back is equal to half the length of the car plus 6X.
Wind tunnel height should be three times the car's dimension.

Vehicle length: 5760

From the middle of the automobile to the front is 2570

Midway between the car's front and rear: 3180

CONCLUSION-

• Working on the Tesla model inspired ideas for the various ANSA meshing tools.
  learned geometry cleanup and surface meshing in great depth. Overcoming obstacles improved one's understanding of tools.
  learned how to use the curve tool and how to utilise curves and points to make a win tunnel.
  discovered the wind tunnel's dimensions and what measurements to use depending on the size of the model
  learned how to utilise the rebuild and move tools, worked on fixing off elements, and learned how to demesh when distinct PIDs with varying mesh lengths are in contact with one another.
