I need to analyse seakeeping motions of a ship in Aqwa. In particular, I am looking at the impact of hydrofoils on motion reduction. I have already imported a hull geometry in .igs format into WorkBench v19 and run the radiation and diffraction analysis. However, when I add the foils (shown below), I encounter problems with the meshing.
To use Aqwa, I need to have a model with surfaces rather than solid bodies. I created the surfaces for the foils. However, I cannot cut out the surfaces of the main hull to remove the portion enclosed by the foils as shown below. If I use the Repair tool of SpaceClaim, I can get the Mesher to create a mesh; however, it excludes the fins. I have tried to use the Combine and Split options to cut the surface where the fins are, following the manual, unsuccessfully. With the Split command, how can I select the hole edge of the fins to cut the hull surface? These are surfaces with a complex curvature.
Many thanks in advance for your help!
