A new app allows yards and owners to use computational fluid dynamics (CFD) to analyse the fuel efficiency of hull design variants at full-scale.

‘Virtual Trial’ application data is available within one week in the form of a web-based report where users can see CFD results and hull lines in 3D and gain more insight into flow details.

“What we have done with Virtual Trial is to let our customers run CFD simulations, without having to invest in CFD expertise,” said Carsten Hahn, product manager at DNV GL – Maritime.

“Virtual trials can be launched in complete anonymity, from anywhere, at any time, by simply uploading the hull geometry file and defining the operating profile.”

As CFD simulation technology has matured it has become a viable alternative to traditional model basin tests, while reducing lead time and costs.

The Virtual Trial application removes the need for expert support by streamlining and automating the CFD simulation process.

Without the need for any CFD specific input, users can conduct fully automated full-scale RANSE (Reynolds-averaged Navier-Stokes equations) VoF (Volume of Fluid) CFD simulations on the resistance and propulsion of their vessel.

Users can upload individual vessel hull forms, run simulations with pre-set parameters and then easily compare their results against the results of similar vessels in the Virtual Trial database.
