Extension of NHWAVE to Couple LAMMPS for Modeling Wave Interactions with Arctic Ice Floes

Developing and testing a tightly-coupled wave-ice model system, including a nonhydrostatic wave model (NHWAVE, Ma et al., 2012) and a discrete element model (LAMMPS; Plimpton, 1995), for simulating wave interactions with arctic ice floes. 2. Using the coupled NHWAVE and LAMMPS models to investigate...

Description
Summary:Developing and testing a tightly-coupled wave-ice model system, including a nonhydrostatic wave model (NHWAVE, Ma et al., 2012) and a discrete element model (LAMMPS; Plimpton, 1995), for simulating wave interactions with arctic ice floes. 2. Using the coupled NHWAVE and LAMMPS models to investigate the relative importance of key physical processes governing the attenuation of wave energy in the marginal ice zone (MIZ). 3. Conducting comparative simulations to evaluate MIZ dissipation parameterizations used by larger-scale ice-ocean models. The study is a collaborative effort with Mark Orzech, Jay Veeramony and Joe Calantoni of the Naval Research Laboratory (separate internal NRL project, funded for FY14-16). The objectives of this study are to 1. extend NHWAVE to incorporate wave interactions with moving obstacles. 2. collaborate with the NRL LAMMPS group to develop matching boundary conditions for both NHWAVE and LAMMPS in a two-way coupling system. 3. collaborate with the NRL LAMPPS group to conduct a numerical study on determining the relative importance of key physical processes governing the attenuation of wave energy in the MIZ.
