Wind, Wave and Tidal Loading

“The latest CFD design tools in conjunction with High Performance Computing (HPC) provide the power to assess real life extreme loads from wind, waves, and tidal forces. This allows more precise engineering to assess the performance of marine structures whilst maintaining reliability and survivability.

ANSYS Fluent

ANSYS Fluent is a Computational Fluid Dynamic (CFD) fluid loading software used to determine the resistance/drag and lift forces from a fluid acting on structure. Typical services provided are:

  • ‘Virtual Test Tank’ using the latest CFD methods to calculate hull resistance and powering requirements
  • Define hydrodynamic forces and moments from hull appendages such as rudder
  • Assess unsteady effects of hull wake exciting vibration modes and sinkage in shallow water
  • Assess the forces and motions on marine structures operating in waves
  • Thrust and torque characteristics of propellers, wind turbine blades and sails
  • Downstream impacts of engine exhausts on cruise ships and ferries
  • Fire and smoke simulations
  • Heating, Ventilation and Air Conditioning (HVAC) thermal modelling

ANSYS HPC

ANSYS HPC turbo charges the computational performance of the CFD calculations by using High Performance Computing (HPC). This enables us to cluster the power of the latest multi-core computer workstations. Currently our license is for 32 core capability available onsite.

 X-Flow

X-Flow is different method of assessing fluid loading on structures and is typically used in highly complex multi-body structures. It uses a Latice Boltzmann method meaning spherical cells geometries are used that simplifies pre and post processing. It is a transient solution using Large Eddy Simulation turbulence theory which has traditionally required huge computational effort. However, this has been simplified by the self adapting meshing which only refines the cells according to their turbulence intensity. When this software is coupled with the latest Supercomputer capabilities offered at the Hartree Supercomputer Centre through our partners OCF, this provides the most impressive and accurate simulations.

OpenFOAM

QED Naval can also offer CFD computations on their Linux platform using OpenFOAM if that is preferred. Given that OpenFOAM in an open source, it can be clustered using all 128 cores or whatever is available onsite from the high-end workstations and compute server.

EPCC

QED Naval also has access to the Edinburgh Parellel Computing Centre which is Scotland’s largest super-computer. Using this capability we can offer customers results in days or weeks rather than months and is a highly effective means of increasing the learn rate and assessing finalised designs.
