L2-Sea¶
Overview¶
The model provides the calm-water total resistance of a destroyer-type vessel as a function of the advancing speed (Froude number) and up to 14 design variables for the shape modification. The parent vessel under investigation is the DTMB 5415, an hull-form widley used for towing tank experiments, computational fluid dynamics studies, and shape optimization. The model is available as an open-source fortran code for the solution of potential flow equations at CNR-INM, MAO Research Group repository github.com/MAORG-CNR-INM/NATO-AVT-331-L2-Sea-Benchmark.

7 |
Fidelity level for the total resistance evaluation associated to the numerical grid discretization. Fidelity goes from 1 to 7, where 1 is highest-fidelity level (finest grid) and 7 is the lowest-fidelity level (coarsest grid). |

‘y’ |
Enabling hydrodynamics coupling with the rigid-body equation of motions for the ship sinkage. ‘n’ enables, ‘y’ disables. |
trimoff |
