Isogeometric Finite Element Modelling of Ideal Non-Linear Free-Surface Flows: Towards total energy conservation

Delft University of Technology has access to a towing tank where a wave maker can generate waves. When generating waves, non-linear start-up effects occur at the start of a wave train which affect the rest of the signal.<br/> The aim of this thesis is to develop a model which can take these effects into account. A numerical modelling approach is...

Isogeometric Potential Flow Analysis of Linear Surface Waves

In numerical methods, correct geometry description and mesh refinement are a challenge. By using a more geometrically based Finite Element Analysis (FEA) type method called ‘Isogeometric Analysis’ (IGA), exact geometry description can be attained, even on coarse meshes. Furthermore, mesh refinement is relatively easy, since no communication with...
