Project 1 : CFD Meshing for Tesla Cyber Truck
Aim: To make the surface mesh and volumetric mesh for Tesla Cyber Truck present in the wind tunnel.
Procedure:
1) First of all we need to clean up the geometry of the Tesla Cyber Truck and then do the mesh.
2) After getting a clear vision, isolating one by one I cleaned the single cone and triple cone to double cone to get the required geometry. 1st I have done with my body clearing the single and triple cones and tries i have cleaned with the option called cut, new (to add faces), delete ( deleting the cons and faces ), hot points projections of cons, and extended option, etc are used for cleaning the geometry.
3) After cleaing the geometry, gone for surface meshing . Now, i have assigned my parts to different PIDs like Body, tires.
4) Now, meshing was done to the Body part with 5mm mesh length surface meshing and also tries with 5mm.
5)Now check the quality of the mesh by hidden option to check the quality if there is to sort by legend colors.
6) Now ready to draw the wind tunnel as per the dimensions, front 3x , back 5x , top 2x , bottom is not required just giving some distance is just see. that x length is 5737mm .
7) create the surface for the bottom part of the wind tunnel and do offset to get the top part and by the new option, we will get all parts.
8) bottom surface will be given 100mm and top surface will be given 500 mm .
9) now for the front surface back surface, and for side surfaces we will use the spacing option such way the from bottom we will increase the element size as we go up by dstart giving 100mm and dlimit to 500mm .
and now we are done with surface meshing for the whole wind tunnel.
Learning Outcomes
1) learned how to clean complex geometry.
2) learned how to mesh complex geometry.
Result: Done with the surface meshing of the Tesla Cyber Truck in a wind tunnel using ANSA.
