A BEM-ISOGEOMETRIC method for the ship wave-resistance problem

Belibassakis, K.A.; Gerostathis, Th.P.; Kostas, Konstantinos; Politis, C.G.; Kaklis, P.D.; Ginnis, A.I.; Feurer, C. (Ocean Engineering, 2012)

In the present work IsoGeometric Analysis is applied to the solution of the Boundary Integral Equation associated with the Neumann-Kelvin problem and the calculation of the wave resistance of ships. As opposed to low-order ...
Construction of smooth branching surfaces using T-splines

Ginnis, A.I.; Kostas, K.V.; Kaklis, P.D. (Computer-Aided Design, 2017-11-01)

Abstract The request for designing or reconstructing objects from planar cross sections arises in various applications, ranging from CAD to GIS and Medical Imaging. The present work focuses on the “one-to-many” branching ...
Isogeometric Boundary-Element Analysis for the Wave-Resistance Problem using T-splines

Ginnis, A.I.; Kostas, Konstantinos; Politis, C.G.; Kaklis, P.D.; Belibassakis, K.A.; Gerostathis, Th.P.; Scott, M.A.; Hughes, T.J.R (Computer Methods in Applied Mechanics and Engineering. Elsevier, 2014)

In this paper we couple collocated Boundary Element Methods (BEM) with unstructured analysis suitable T-spline surfaces for solving a linear Boundary Integral Equation (BIE) arising in the context of a ship-hydrodynamic ...
Shape-optimization of 2D hydrofoils using an Isogeometric BEM solver

Konstantinos, Kostas; Ginnis, A.I.; Politis, C.G.; Kaklis, P.D. (Computer-Aided Design. Elsevier, 2016-06-29)

In this paper, an optimization procedure, based on an Isogeometric BEM solver for the potential ow, is developed and used for the shape optimization of hydrofoils. The formulation of the exterior potential- ow problem ...
Shape-optimization of 2D hydrofoils using an Isogeometric BEM solver

Kostas, K.V.; Ginnis, A.I.; Politis, C.G.; Kaklis, P.D. (Computer-Aided Design, 2017-01-01)

Abstract In this paper, an optimization procedure, based on an Isogeometric BEM solver for the potential flow, is developed and used for the shape optimization of hydrofoils. The formulation of the exterior potential-flow ...
Ship-Hull Shape Optimization with a T-spline based BEM-Isogeometric Solver

Kostas, Konstantinos; Ginnis, A.I.; Politis, C.G.; Kaklis, P.D. (Computer Methods in Applied Mechanics and Engineering, 2014)

In this work, we present a ship-hull optimization process combining a T-spline based parametric ship-hull model and an Isogeometric Analysis (IGA) hydrodynamic solver for the calculation of ship wave resistance. The surface ...
VELOS: A VR Platform for Ship-Evacuation Analysis

Ginnis, A.I.; Kostas, Konstantinos; Politis, C.G.; Kaklis, P.D. (Computer-Aided Design. Elsevier, 2010)

“Virtual Environment for Life On Ships” (VELOS) is a multi-user Virtual Reality (VR) system that aims to support designers to assess (early in the design Process) passenger and crew activities on a ship for both normal ...
