Project 1 : CFD Meshing for Tesla Cyber Truck

ANSA Tool Test

Aim:

• To perform a geometry clean-up on the given geometry of the Tesla Cyber truck.
• To assign different PIDs to different components.
• To create an enclosure of the given dimensions.

Methodology

• Geometry clean up:

1. The geometry was checked for single-cons and triple cones and bad surfaces
2. These errors were rectified by using the following commands.

• Delete: This was used to delete any entity which cause geometrical errors such as overlapping surfaces, Single and Triple coons.

• Extend: This is used to extend single coons to another face.

• Intersect: This is to intersect between two faces.

• New: This can create new faces between coons.

• Curve: To create a curve between two hot points.

• Project: To project a hot point from one edge to another.

• Fill hole: To fill a closed hot of a specified tolerance.

• Cut: To cut a face into parts

• Creation of enclosure:

1. To create an enclosure of defined dimensions around the cybertruck which defines the fluid region.

Length		6000mm
front	5*Length	30m
rear	15*Length	90m
Side	5*Length	15m
top and bottom	5*Length	30m

• Assigning PIDs

1. Each surface was defined with the respective PIDs, different PIDs assigned are given below,
1. Windshield
2. Windows
3. Body
4. Tyres
5. Top
6. Bottom
7. Sides
8. inlet
9. Outlet

• Meshing

1. Initially, surface meshing was performed on different PIDs on the airplane whose target lengths are shown below
   1. Windshield: 20mm
   2. Windows: 20mm
   3. Body: 20mm
   4. Tyres: 10mm
   5. Enclosure 500 mm

• Volume detection

1. After performing the surface mesh, the volume of the fluid surface was detected by using the ‘AUTO-DETECT’ option under the volume meshing option.

1. The fluid volume was extracted

Conclusion:

The Tesla cybertruck model was meshed in ansa after cleaning up the geometry and assigning different PIDs
