BMW M6 Meshing   Symmetry in Model: Since the car can be treated to be symmetric about a plane except for the tyres, it is possible to remove the surfaces on one side, and work on only the other side. Finally it can be symmetrically mirrored to complete the geometry. Stage 1:Body Cleanup Objective: The model is cleaned…

Grid Dependency and Mesh Convergence: The solution to a FE problem is dependent on the mesh size. The obtained FE solution tends to the actual solution as the mesh is made finer, but with a consequent increase in computing time. It is therefore necessary to reach an optimum mesh size to obtain a fairly accurate solution…
