We've started the journey with the novel hull resistance solver, which soon will be enriched by adding a solver for the dynamic equilibrium (trim and sinkage). This will be the fastest validated CFD solver for vessels, that is also runnable inside the browser.
In between tests of the equilibrium solver, we're going to add already tested propulsion calculators. The first in the row is the Wageningen B-series calculator, which dynamically outputs the characteristics. Next follows Gawn, KCA, and optimizers.
By the way, we get a lot of feedback concerning the resistance. Please feel free to share your ideas and wishes for the propulsion, seakeeping, etc.!
Now the resistance calculator
more accurately implements the boundary layer and wake effects on the wave resistance. In addition, we've added the initial implementation for demihulls! Please see the changelog
Coming soon: Rhino plug-in, dynamic trim and sinkage to reach high displacement speeds, and then planing speeds!
Per your requests, the Rhino plug-in is on its way. This April is going to be full of surprises with new features implemented in both online versions and within Rhinoceros.
The initial version of the resistance calculator is now added to the website. The calculator is applicable for most types of ship hulls that sail in the displacement mode, without deeply immersed transoms.
For the prediction of ship resistance in the preliminary stages of the ship design process, naval architects often use methods that are less complex and expensive than CFD simulations and experiments. Michell's thin ship theory can be used to quickly evaluate wave-making resistance, although, the original theory gives poor estimates for conventional hulls. In this calculator, techniques to improve the theory are introduced that account for viscous and non-linear effects. The improvements are validated by numerical simulation on profoundly different hull forms.
The website is being set-up as a skeleton for adding various content, i.e. the website will provide easy, quick and user-friendly access to a large quantity of tools for naval architects and marine engineers.
