Advanced analysis involves the efficient use of industry standard tools to provide solutions to complex engineering problems.
We work closely with our clients to understand the issues they want to address and ensure that we provide a focused solution. We work within the wider structural team of structural engineers and designers so that at Optimus is a one-stop-shop for providing structural engineering solutions.
The software packages we use are:

We can offer the following capabilities:

  • Non-linear finite element analysis including contact problems and non-linear materials
  • Blast loading, impact analysis and dropped objects
  • Transient dynamic and natural frequency analysis
  • Offshore renewable energy structures
  • Offshore concrete structures
  • Wave, wind and current loading
  • Fracture and fatigue assessment
  • Fluid-Structure interaction
  • 3rd party review and verification
