When first used within Emirates Team New Zealand, it was simply known as “Dan’s VPP”. As its use grew, it clearly needed its own identity. Dan spent a weekend trying to come up with a catchy name, but the one he chose was ridiculed by the team, and will never be mentioned again!
To drive Gomboc in dynamics mode as a simulator, it’s easiest to use a steering wheel. Any wheel that supports DirectInput can be used – although we may well be able to add a customisation to run something else.
For a desk set-up, we recommend a Logitech G29, which is relatively inexpensive, has force feedback, and has plenty of buttons to which sail controls can be assigned.
Yes, if you’re not keen on building your own Gomboc boat model, we’d be very happy to build a model for you. Typically, it would take around 40 – 80 hours to build a model, and our time would be charged at 85 EUR/hour. However, it is very dependent on the data provided to us; a complete set of data clearly specified makes the job a lot easier!
Yes. Any data that provides forces – and optionally other outputs – as a function of parameters can be used. The data should be be organised into a PZ CSV format, where the columns represent parameters, forces and other outputs, and each row reports a condition (e.g. CFD run). As an example, you may have a matrix of 50 CFD runs for a hull. Columns could be Speed, Sink, Trim and Leeway as Parameters, and Fx, Fy, Fz, Mx, My, Mz as Outputs, and each row would represent the result of one CFD run. Additional columns might be Wetted Surface Area, Viscous Drag, Wave Drag, etc. These additional columns won’t affect the Gomboc solution (unless you use them to compute some other forces) but will be output for information.
Gomboc has several built-in methods for creating a smooth fit surface to the input data, and interpolating over that fit to estimate a solution at any combination of parameters.
A paid Gomboc licence includes support to help you get set-up and answer any questions you have using the software, over the duration of the licence period.
If you need more extensive support, for example, building models or making customisations to suit your project, this will be charged at 85 EUR/hour.
Yes. We offer a floating licence capability option which allows to move Gomboc from one machine to another an infinite number of times. Please let us know if you are interested in this option.
If you experience hardware issues but you did not subscribe to the floating licence option, we can exceptionally delete your existing licence and create a new one to be used on another machine.
