Started propelling, validating dynamic trim & sinkage

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.!

Resistance of displacement ships

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.

Website up & running

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. This website is not a static site: it is continuously updated and checked for quality. User suggestions and requests are welcome. Our team is going to answer the suggestions and submit them to evaluation. You can contact us by using the contact form.
