Project 1 : CFD Meshing for Tesla Cyber Truck

AIM: To perform the CFD Meshing for Tesla Cyber Truck

Procedure:

• Geometry Cleanup Procedure
• Delete all the additional surfaces which are not required; such as ring features which are mainly created by the designer verticals for the creation of drawing
• Also delete all the unmeshed surfaces
• Also delete all the overlap surfaces
• Fill all the Open faces via fill holes or new surface creation

• Assign Required PID's
• All the esential PIDs have been assigned, as follow:
• 

• Meshing (Truck)
• Initially two PID has been created such as for Body and Tyre & Rim
• The target length has been set to 5mm for both bodyand tyre & rim (min lenght to 1mm and max lenth to 8 mm , as in quality criteria)
• the following are the mesh view of Body (having total triads=3640510), and respective Hidden Wireframe view as well, showing zero offset
• 
• the following are the mesh view of Tyre & Rim (having total triads=1057738), and respective Hidden Wireframe view as well, showing zero offset
• 
• After this Wind Tunnel Has been constructed.
  
  
• Construction & Meshing of Wind Tunnel
• Initially the measurement of body in side way along the length has been taken using measure tool and assign a value of x=5955mm
• then, a reference point has been constructed at the bottom centre point of the body.
• then front and rear point has been constructed by taking refernce as such above point at a distance of 4x and 6x respectively
• then, curves has been generated along such point and new surface has been constructed and offset such surface to the location of 3x from the top of the body surface, and further walls has been generated.
• the following are the view of wind tunnel:
• 
• Then assignment of PID has been done and meshing has been performed over it,
  for the top surface set the specific target lenth of 100mm and min and max length to 120 and 80 respectively as quality criteria.
  for the bottom surface set the specific target lenth of 20mm and min and max length to 25 and 15 respectively as quality criteria.
  For the side walls, variable meshing size has been assign via spacing taking geometric factor of 1.1 and dmin as 20 and dlimit as 100 and direction started from bottom to upper side and local as a target lenth has been set.
• the mesh view of wind tunnel are as follow (having total triads of 8842186):
