Project 1 : CFD Meshing for Tesla Cyber Truck

PROJECT_1:- CFD MESHING FOR CYBER TESLA TRUCK:-

AIM:- Geometrical clean up of the Tesla car and then we have to do the geometrical clean up of the model.

OBJECTIVE OF THIS PROJECT:- The project is consists of 4 process

1. Topo clenup

2. Given the component names.

3. given the PID'S

4. MESHING of the given componenets.

5. wind tunnel creation

IMPORTANCE OF GEOMETRY TOPO CLEAN UP:-

1. FIRST We have import the geometry of given model.

2. we have use the top view option

3. we have insert the hotpoints

4. we have use the planecut option and create the middle line.

5. we have form the intersection line

6. we have used the universal delete option

7. cut the half section view.

8. used the topo option, some errors are rectified.

9. We have used the coons option and fill hole and created the new surfaces.

10. In tyres part we have remove the extra cylinders and the tyres are only single volume.

11. after that we have used the copy option and symmetry both sections

OUTPUTS OF GEOMETRY CLEAN UP:-

MESH OF COMPONENTS AND ITS IMPORTANCE:-

1. First we have given to each and every componet of individual names.

2. we have create the pids of each and every component with the help of face selection.

3. we have used the mesh quality criteria each and every component.

4. The names of the given model components are window_shield, windows, front tyres, back tyres, body.

5. we have taken the valures are 3,3,2,2,1 mm are taken as permiters and macorns.

6. we have used skewd and maximum length and maximum length.

skewed:-Skewness is the deviation between the optimal cell size to the existing cell size. The range of skewness is between 0 (ideal) to 1 (worst). Highly skewed cells are not preferred due to the poor accuracy they cause within the interpolated regions.

Maximum and minimum we have to taken because it is distance between the nodes and elements.

MESH OUTPUTS:-

3. WIND TUNNEL CREATION:-

In this challenge we have taken length of the truck. The length was 6000 and create the mid point and dia of the 3000 f the truck , we have create the points with the option of relative option. we have created the the top surface points and botton surface points. we have used the create option take the line and joint the all surfaces with the help of coons options.

we have the create the names top, bottom, front, rear and side surfaces after that we have give individual pids.

wind tunnel ouputs:-

Conclusions:-

1. The imported geometry all errors are topo cleanup

2. surface meshings are done as given values.

3.Worked with the errors occured in the Mesh.

4. Created a wind tunnel For external aerodynamic analysis.

5. All components are surface meshing done as per given components.

6. skew method are used of each and every component.

7. minimum length and maximum length are used each and every components.
