CLEANING UP AND MESHING OF BMW M6 FOR SIMULATION IN A WIND TUNNEL

Objectives :

1) To clean up the topological errors.

2) To clean the geometry using different tools.

3) Running diagnostic check.

4) Use of Boolean operations for better visuality of the geometry.

5) Setting up PIDs.

6) Generating mesh using uniform length for different components of the car.

7) Create a wind tunnel for the car for simulations.

Procedure :

1) Import the given CAD file. After importing the CAD file, go to check manager to locate the missing holes, surfaces and other geometrical errors.

2) Deleting the half portion of the car for better visibility access to the minor errors in the car geometry. After rectifying all the errors we’ll later impose symmetry to the car geometry which in turn results into cleaned up geometry as a whole.

3) Assigning PIDs to the respective components of the car

4) Setting up the mesh parameters.

5) Assign given uniform length to the respective parts and mesh the entire BMW M6 car geometry.

6) Correcting all the errors and using check manager to confirm the geometry check

7) Assigning Presentation Parameters and Mesh Quality Criteria

8) Symmetry is imposed by copying the entities of half portion of the car geometry. Symmetry is imposed by selecting 3 points on the same plane.

9) Creating Wind Tunnel for working on simulations of the car geometry. It’s length should be four times the front, 6 times the rear, 3 times the top of the car and bottom close proximity with the tyres. One times from the centre plane for left and right sides.

Conclusion :

1) Successful geometrical clean up.

2) Various tools used to clean up all the holes and faces.

3) Assigned PIDs to the respective components.

4) Assigned given uniform length and meshed the entire BMW M6 car geometry.

5) Created the wind tunnel for aerodynamic simulations.
