Modelling & Analysis

Key to Understanding your Design

The Blackfish team are familiar with a wide variety of modelling and analysis tools to suit any situation. Design enhancements and recommendations can be achieved through pro-active modelling and analysis feedback. The model assumptions are always well documented throughout this process and can be captured in a full analysis report.

Modelling

Blackfish have experience producing numerical models of engineering systems and subsystems to enable computerised analysis of designs. Blackfish use MATLAB & Simulink to create bespoke system models to better understand the forces, moments and behaviour under certain conditions.

Blackfish also have extensive experience with DNV-GL's Bladed and Tidal Bladed software codes for the modelling of wind and tidal turbines, respectively. We are able to generate turbine models from scratch and produce turbine performance and load predictions to certification standards.

Additionally, Blackfish have several in-house modelling codes developed to understand physical phenomena, such as our in-house blade element momentum code and CAD based buoyancy and trim solver.

Finally, we can offer tidal and wave resource modelling using TELEMAC fluid flow modelling software.

Analysis

Finite element analysis is a computational tool that enables engineers to assess the effects of external influences on a component during the design phase, reducing the need for expensive testing and redesign. FE analysis can also be used iteratively to optimise weight, cost and other design parameters.

Using the very latest ANSYS™ Mechanical Pro software, Blackfish can bring finite element analysis into your workflow, giving you a step-change increase in information to help you make those all-important design decisions.

To fully understand the structural behaviour of your design, Blackfish can, amongst other things, analyse:

Fatigue life | Safety factors | Heat transfer

Modal frequencies | Deflections Bolted joint strength

Weight reduction opportunities

Blackfish Optimisation Service

Blackfish have multiple tools and experience at our disposal to optimise a chosen design. This optimisation can increase performance, reduce weight, reduce cost and much more. Our capabilities include:

A differential optimisation code, based around the principles of genetic evolution

  • Used in multiple, highly successful blade optimisation projects
  • Great for multi-objective problems
  • Can be adapted to any system model
  • Define your own ‘optimal’

Autodesk & ANSYS topology optimisation

  • Good for weight reduction
  • Stress optimisation
  • Optimisation for direct load-paths
  • Achieve minimum wall thickness
  • Optimise for cyclic symmetry
  • More information on the ANSYS site
