Week 4 Challenge : CFD Meshing for BMW car

Aim:

For the given model, check and solve all geometrical errors on half portion and Assign appropriate PIDs. Perform meshing with the given Target length and element Quality criteria. After meshing the half model, Do symmetry to the other side.

1. Target lengths for the different parts of a model are as follow:
2. Body - 3 mm
3. Lights - 4 mm
4. Grills - 1 mm
5. Rims and Tyres - 2 mm
6. Optical Rear view mirror - 2 mm
7. Window - 2 mm
8. Silencer - 3 mm
9. Logo - 1 mm

Procedure:

1) TOPO CLEANUP

2) SURFACE MESH

3) QUALITY CRITERIA

4) WIND TUNNEL

5) VOLUMTERIC MESH

AGENDA OF THIS PROJECT: CREATING VOLUME

1) VOLUME INSIDE THE CAR.

2) VOLUME INSIDE TIRES.

3) CREATING WINDTUNNEL.

4) VOLUME BETWEEN CAR & WIND TUNNEL.

Topo Cleanup completed for entire goemetry, double cons maintained throughout the geometry no single cons present in the geometry, after geometry cleanup PID created for every part, after performing geometry cleanup meshing done for every PID, each and every PID we ensured that the OFF elements tobe zero, and used some new features

Report:

Conclusion:

For the given model, checked and solved all geometrical errors on half portion and Assigned appropriate PIDs. Performed meshing with the given Target length and element Quality criteria. After meshing the half model, Done symmetry to the other side.
