Project 1 : CFD Meshing for Tesla Cyber Truck
Aim:
solve all geometrical errors and Assign appropriate PIDs. meshing with the suitable Target length and element Quality criteria.
Procedure:
step1:
- check the units.
- click TOPO for minor errors of single CONS.
- geometric check
step2:
due to the symmetric shape of model ,can cut the model into half part .
plane cut>single >select 3points>ok
step3:
- deleted the half part with more errors.
- check the geomatrical errors.
- cleared the geomatricerrors.
step4:
assign the PIDs
step5:
set the quality criteria with min length=0.5mm and max length=7mm.
mesh the window and tyres with target length as2mm
mash the body with target length min=1mm and max=5mm.
step6:
- mirror the half part.
- check again the geomatric errors.
- cleare the errors.
step7 :
- check the quality criteria.
- mesh the full model.
Step7:
creat the wind tunnel
- create the point below the model with 600mm.
- with reffrence the creaed point ,creat the front and bcak with 25650mm and37050mm respectively.
- create the side piont on both side with 6950mm.
- create the face using the created points.
- created the top face with reffrence with bottom face.(use offset>face> selet face and direction).
- create the side face.
- create the side face.
step8:
mesh the wind tunnel .
bottom face with 100mm
top face with 300mm
side face with growing mesh with Dstart=100mm
and Dlimite=300mm.
final view with all PIDs
Result:
finer mesh with better quality criteria for the given model.
