New Paper on Faster Hydro­dy­namic Opti­miza­tion of a Catamaran

A new paper on ​“Appli­ca­tion of Radial Basis Func­tions for Par­tially-Para­met­ric Modeling and Prin­ci­pal Com­po­nent Analysis for Faster Hydro­dy­namic Opti­miza­tion of a Cata­ma­ran” by FRIEND­SHIP SYSTEMS authors Stefan Harries and Sebas­t­ian Uharek has been pub­lished in the Journal of Marine Science and Engi­neer­ing (JSME) – Special Issue: Hydro­dy­namic Design of Ships.

The paper shows the appli­ca­tion of a flexible par­tially-para­met­ric modeling approach on the basis of radial basis func­tions (RBF) for the mod­i­fi­ca­tion of an existing hull form. Since the RBF approach may poten­tially intro­duce quite a few degrees-of-freedom (DoF), a prin­ci­pal com­po­nent analysis (PCA) is utilized to reduce the dimen­sion­al­ity of the design space. PCA allows the delib­er­ate sac­ri­fice of vari­abil­ity in order to define vari­a­tions of interest with fewer vari­ables. The aim of com­bin­ing RBFs and PCA is to make sim­u­la­tion-driven design (SDD) easier and faster to use.

Shape morphing allows you to easily import an existing geometry model and reshape your design with regards to the flow and struc­tural per­for­mance. Read our latest blog post ​“Fast and Effi­cient Geometry Opti­miza­tion with Morphing” for a com­par­i­son of the dif­fer­ent morphing approaches in CAESES 5 and how it offers intu­itive and exact shape mod­i­fi­ca­tions that can be set up in a matter of minutes.
