My current research focus in on the NUMO project - Non-hydrostatic Unified Model of the Ocean (a child project of NUMA, read below). The goal of the project is to develop an ocean model capable of resolving ice-sheet / ocean interactions within narrow and elongated fjords of Greenland. To achieve that I use a high-order discontinuous Galerkin method with variable resolution grids and local non-conforming adaptation capability to represent the fine-scale ocean interactions with a marine-terminating glacier and their impact on general ocean circulation while maintaining affordable computational cost. For more details about the project, please visit the NUMO website.
During my postdoc at NPS, I have been involved in the development of Non-hydrostatic Unified Model of the Atmosphere (NUMA), which became a framework for NUMO. I have been working on implementing non-conforming adaptive mesh refinement capability in NUMA, as well as improving the efficiency and scalability of the model.
NUMA is a 3D model of the atmosphere. However, we have also developed a 2D Euler and shallow water equation solver (NUMA2D) that works both in limited area mode and on the sphere. This model can (and is) used for rapid prototyping of new ideas and graduate student projects. It includes wetting and drying for inundation problems, dynamically adaptive non-conforming mesh capability and a unified spectral element / discontinuous Galerkin framework. Please contact me if you are interested in using NUMA2D for your research and teaching.
