Abstract
The vast majority of numerical wave tank applications are solved using finite volume-based, volume of fluid methods. One
popular numerical modelling framework is OpenFOAM and its two phase solvers, interFoam and interIsoFoam, enabling
the simulation of a broad range of marine hydrodynamic phenomena. However, in many applications, certain aspects of the
entire set of possible hydrodynamic phenomena are not of interest and the reduced complexity could allow the use of simpler,
more computationally efficient solvers. One barrier for the application of such alternative solvers is the lack of suitable
wavemaking and absorption capabilities, which this paper aims to address. A wavemaking and absorption methodology is
presented, which can be applied to different solvers using the same fundamental concept. The implementation is presented for
interFoam and interIsoFoam, as well as two other solvers whose use as numerical wave tanks has not previously been reported
in the literature, shallowWaterFoam and potentialFreeSurfaceFoam. Parameter studies are performed to guide the user in the
use of the methods. Example applications for two industrially relevant test cases are demonstrated; a multi-frequency wave
packet focused at one position over flat bottom and regular waves propagating over a submerged shoal. All solvers yielded
useful results, but some complex wave transformations in the shoal case were only resolved by the VoF methods. Alternative
methods beyond the already well established VoF methods seem worth considering because potential for significant reductions
in computational effort exist.
