Hello Everyone,
I have been trying to create an unstructured mesh around a Formula 1 model. I have tried using the Delaunay method to create a volume mesh around the car but the volume mesh created exceeds my defined test space. The issue is indicated in these photos.. I don't seem to understand why this happens. There might me something that I am doing wrong in my set up process so I will list the steps that I took in creating the mesh. 1. I imported the geometry, Then created the Inlet, outlet and Farfield parts. Created a body called Fluid. 2. I used the global mesh setup to define my max element size to be 4. (The test space is 10 by 20 by 10) 3. In shell mesh setup, I chose All tri and Patch Independent. 4. In volume mesh set up, selections are tetra/mixed, quick (Delaunay) and scaling factor:1.2 5. In part mesh setup, I defined the max element size on the car to be 0.05 and left all other parameters to be 0. 6. Compute mesh; surface mesh and generated a surface mesh. (image below) 7. Finally Compute mesh> Volume mesh I chose tetra/mixed, quick (delaunay) Volume part name: Inherited I would be extremely grateful if I someone can show me where I am going wrong. Thank you very much in advance! Best Regards, Manahara |
