Project 1 : CFD Meshing for Tesla Cyber Truck

AIM - CREATING VOLUMETRIC MESHING FOR TESLA CYBER TRUCK AND WIND TUNEL

PROCEDURE - For creating volumetric meshing of Cyber Truck and wind tunel, there have some steps, following steps are mention below,

1.Topological Cleaner of Tesla Cyber Truck

2.PID Creation

3.Quality Criteria for Tesla Cyber Truck

4.Surface Meshing of Tesla Cyber Truck

5.Wind Tunel creating and Surface meshing

6. Volumetric Meshing

Above steps, detail description mention below,

1.Topological Cleaner of Tesla Cyber Truck -

I have open given model, and found there have present only single cons, So i do TOPO to fix it to double cons by Box selection.

After to TOPO, model have been fixed but, there have present some single cons

Now i have found, thre have some surface missing, thats why single cons are visible,

Now i have created new surface , by NEW option(Coons, Fitted or Fiill Hole)

Now, Surface create has been done, and Now there have no single cons and tripple cons present there checked by wire frame mode

But there have some unwanted surface present, need to remove that, because we need single volume of the model

Now i have removed all unwanted surfaces one by one

After that, I have checked Geometry check, found ok.

Now, TOPO logical cleaners work has been completed. Now model is ready for different PID creation for different parts.

2.PID Creation -

Now i have created new PID, 1. - Window

2. - Rims and Tyres

3. - Body

And i have applied for these for PID

After appling new PID, I need to delete OLD PID, which is not required.

Then, i have deleted old PID by force fully by COMPRESS option.

3.Quality Criteria for Tesla Cyber Truck -

After completing NEW PID, Now for surface meshing, i need to creat Quality criteria procedure. All calculatio type will be FLUENT type, and value is asper given in week 4 challenge

4. Surface Meshing of Tesla Cyber Truck -

After completeing Quality criteria, now model is ready for surface meshing,

Now i have given for all PID - BODY - Target Length - 3 Max - 5 Min - 1

RIMS AND TYRES - Target Length - 3 Max - 5 Min - 1

WINDOWS - Target Length - 4 Max - 5 Min - 2

Now surfce mesh has been completed for all PIDs.

5.Wind Tunel creating and Surface meshing -

Now i have checked total length and total width of the TESLA CYBER TRUCK

Now i have created point at bottom side and first creating surface at bottom side

after that i have creat another points at Front side, length - 26100mm

after that i have creat another points at Rear side. length - 38800mm.

after that i have creat another points at Left and Right side, length - 5900mm.

Now , all points have been created to make a new curves and create new surfaces.

Now i have created top surface by offset option.

Now i have deleted all 4 curves and all points.

now i have created all surface one by one

After creating surfaces, I have to creat new PID for different all 6 surfaces. and also applied PIDs for these surface.

Now its time for surface meshing.

First i have done top and bottom surfaces, surface mesh

TOP SURFACE - Target Length - 100 Max -120 Min - 80

BOTTOM SURFACE - Target Length - 20 Max -25 Min - 15

Now, I have done surface mesh for side, front and rear surface

Now, surface mesh has been completed of WIND TUNEL.Now i will go for volumetric mesh process.

6. Volumetric Meshing -

Now i will do volumesh mesh and select Define -> Whole db

After that , i found different different volume and keep one volume which is selected model and wind tunel and rest volume i have deleted.

Now when i select remesh, then it will become volumetric mesh.

Note - ANSA file can't be uoloaded because it become very big file,more that 1.5GB
