DNV GL has introduced a new ‘Virtual Trial’ application, using simulated computational fluid dynamics (CFD) data to analyse, compare and benchmark the fuel efficiency of different hull designs before they are constructed.
The results are made available within one week, DNV GL says, via a web-based report where users can see the CFD results and hull lines in 3D. Users can upload individual vessel hull forms, run simulations with pre-set parameters and then compare their results against the results of similar vessels in the Virtual Trial database.
“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.”
