Structural FEA Deep Dive: Proving Complex Structures Before They're Built

Structural finite element analysis (FEA) is a core area of expertise at Blackfish Analysis, supporting clients across design validation, structural integrity assessment and engineering optimisation.

Structural problems vary widely, from large offshore towers and platforms under global loading to complex assemblies involving fasteners, bearings and cables. Real designs also carry manufacture and assembly effects such as welds, preloaded joints and interference fits, each needing an analysis approach matched to its complexity and risk.

Blackfish Analysis builds structural models in Ansys Workbench, ranging from simplified beam representations to detailed shell and solid geometry, working from client CAD or from scratch for early feasibility studies. Analysis covers stress, strain, deformation, fatigue life, vibration, buckling and dynamic loading, accounting for material, geometric and contact nonlinearities where needed. Every model passes through internal quality control and convergence checks before results are issued.

Clients get analysis matched to how their structure will actually behave in service, with results they can view directly through the free Ansys Viewer tool even without an Ansys licence, and the confidence to move forward with manufacture or deployment.
