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
PROCEDURE
The given model is shown below
Lets do Topo to clear the single cons, then the model looks like this
We can do plane cut to cut the vehicle into 2. Otherwise we can do it without cutting.
After cutting, the model looks like this
Check whether the cutting is done properly and do alignments of some parts to make it as symmetry.
Remove unnecessary surface that cause triple cons.
Handle these parts at the cutting part to make it as symmetry.
These parts are at the front of the truck.
Then isolate the truck like this and then clear the intersection error
We can go to clear the error at shaft and tyre.
Its better to delete the shaft.
After clearing it fill the hole of tyre
Do the same for other tyres also
Now, only one intersection error is there. Lets clear it
Intersection error and other errors are cleared
Now, most of the errors cleared. Let's see if we can clear warnings
Maximum errors and warnings are cleared. There are convex cons in tyres which is design part. So, ignoring it.
After that assign PIDs
Mesh Glass & window and Tyres by 2 mm and mesh Body and Light by 3 mm.
Use the following quality criteria
Use CFD mesh
Use the following mesh parameters for Glass & window and Tyres
After meshing, the PIDs looks like this with no off elements
Use the following mesh parameters for Body and Light
After meshing, the PIDs looks like this with no off elements
After that, the half model looks like this with no off elements
Lets create symmetry on other side
After doing symmetry, the entire model looks like this with no off elements
Let's create a wind tunnel from the sides as shown below
The length of the tesla model car is taken as x, which is 5910 mm.
The wind tunnel is created like this similar to BMW challenge and also mesh it similar to BMW challenge.
After meshing, the wind tunnel looks like this
Also, the geometry is having no error. Only mixed cons, concave and convex cons as warning
I m not going for Volume mesh. But I m just checking whether my model is suitable for Volume mesh
6 closed Volumes I found.
1 closed Volume is the volume of the truck.
Other 4 are the Volume inside the 4 tyres.
Other 1 is the Volume between truck and wind tunnel. We required that Volume only. So, we can delete other Volumes for doing Volume mesh
