Project 1 : CFD Meshing for Tesla Cyber Truck

Aim:

- To check and solve all geometrical errors on half portion and Assign appropriate PIDs.

- To Perform meshing with the given Target length and element Quality criteria.

- To create CFD Meshing for Tesla Cyber Truck.

Target length for surface meshing,

Lights - 4 mm

Body - 3 mm

Rims and Tyres - 2 mm

window - 3 mm

For Quality Criteria,

We unchecked all other Criterias other than Skewness, max and min length.

There is difference between max and min for quality criteria and target length, max and min(target length) changes for each part of the model. But for quality criteria max and min is same for the entire model.

Skewness given for the model - 0.5

Skewness :

We can say that skewness is an allowable deformation of the shape of a 2D element when compared to ideal element. Ideal shape of tria element is Equilateral triangle.

minimum length - 0.1mm

maximum length - 7mm

Procedure :

Before starting further process, we need to know the unit dimension and then resolution of the Tesla Cyber Truck model is distorted for better resolution we change the perimeter length in the mesh generation tool.

In this given model, there are a lot of typo errrors which can be cleared using typo command.

* Topo / Geometry clean up :

When geometry is checked, we had lots of errors, single coons and 18 Intersection of PID's ,

After them up with the help of various tools for every single part, In the beginning we took care about Grills then logo and then rear view mirror, etc...

As this car model is going to undergo CFD simulation - external flow analysis, we can delete faces that are internal which in turn is no need for the external flow simulation.

Setting the PID names,
