Project 1 : CFD Meshing for Tesla Cyber Truck

Aim: For the given model, check and solve all geometrical errors and Assign appropriate PIDs. Perform meshing with the suitable Target length and element Quality criteria.

Given Model:

Now Go to mesh deck>Length>perimeters>select all model>enter length as 1mm>ok.

this will create smooth surface.

Geometry cleanup.

Select topo> select all surface and click ok.

Now create the missing new surfaces and delete the unwanted surfaces from the body of the car.

Surface Meshing of the car:

Wheels:

Select the pid wheels

Enter the quality criteria and mesh parameters and generate the mesh of length 3mm.

Select the pid Body

Enter the quality criteria and mesh parameters and generate the mesh of length 5mm.

Wind tunnel creation:

Dimensions

Length of car :5894

Side wall of wind tunnel: 5894

Bottom surface of wind tunnel: -560

Rear surface of wind tunnel: 35364+5894=41258

Front surface of wind tunnel:23576

Top surface of wind tunnel:19052

Wind tunnel surface meshed Meshed Variable mesh used with 100 units at bottom face and 1000 units at top face.

Now we can proceed for the volumetric meshing:

Select tetra mesh and the define>whole database>ok

Conclusion

Geometry cleanup of the model done by creating new surface and deleting the unwanted surface.

Surface meshing of the car was done.

Wind tunnel created as the standards.

Surface meshing of wind tunnel done appropriately.

Then common volume estrated for volumetric meshing.
