A Mechanical Freelancing Hub

We need a skilled FEA pre-processor to prepare two BIW models—the current design and a version with several ribs removed—for a global stiffness comparison. We will supply the CAD assemblies; your task is to deliver production-ready HyperMesh (or FEMAP) files that let me run the analysis as soon as they land on my desk.

Scope of work:

• Geometry cleanup: remove duplicate surfaces, heal surface holes, and simplify any unnecessarily complex features that could compromise mesh quality or inflate element count.

• Midsurfacing: extract accurate mid-planes for all relevant stampings and ensure thickness attributes are mapped correctly.

• High-quality mid-plane shell meshing: target a uniform element size, keep warpage and aspect ratio within accepted automotive BIW limits, and resolve all flow-paths and flange regions so panel stiffness is preserved. Hybrid mesh controls are fine as long as the finished mesh passes standard quality checks.

• Model hand-off: deliver organised component groups, property cards, and part IDs that match my naming convention so I can drop the decks straight into the solver.
