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.

ANSA File:

Procedure:

Then go to Check-geometry to identify the errors. After that delete some unwanted surfaces and create some new surfaces as required to complete the geometry.

Then go to quality criteria select appripriate option and change the minimum and maximum mesh lenght as per the part required and then go to the mesh parameter option to change the mesh type as Tria and the enter the appropriate mesh length.
After that start meshing the geometry part by part as per the required mesh length using spot mesh option.

Mesh length= 2mm

Parts : Windows

Quality Criteria:

Mesh Parameter:

Surface mesh:

Mesh Length = 4mm

Parts : Tyres, Lights, Body

Quality Criteria:

Mesh Parameter:

Tyres:

Lights:

Body:

After the meshing there will be some off elements present, some of the off elements can be solved by using reconstruct option and the remaining off elements should be solve manually by using move option.

After finish the surface mesh of Tesla Cyber Truck the wind tunnel surfaces must be created based on the size of the model.
Then create PID's for Tunnel surfaces and then assign them.

After that change the quality criteria and mesh parameters for base and top surface of the Tunnel as required. Then mesh the surfaces using spot or CFD mesh.
The side surfaces, front and back surfaces mesh can be done by using spacing option to increase the mesh size from bae surface mesh size to top surface mesh size gradually.
After the surface meshing on Tunnel go to voumetric mesh and define the volumes.Delete the unwanted volumes and keep the required volumes to do the volumetric mesh.
