In this project, we want to model permeable breakwaters numerically using OpenFoam and deal.II. In particular, we want to investigate relatively small-scale effects (at the perforations) during regular and irregular sea-state conditions. <\/p>\n\n\n\n<p><strong>Figure 1<\/strong> shows the OpenFoam 3D cylinder test case. The idea is to extend the 2D breakwater test case in OlaFlow (a C++-based OpenFoam library based on the finite volume method) to 3D, varying various factors such as wave conditions and porosity.<\/p>\n\n\n\n<p>In another part of the project, simulations will be run with a Navier-Stokes code based on the C++ deal.II library for finite element methods (see <strong>Figure 2<\/strong>). The code is based on cell-based Vanka smoothing and uses a parallelised multi-grid approach. It will be adopted and extended for breakwater applications.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Funding<\/strong>: Helmut Schmidt University; since 01.12.2022<\/p>\n\n\n\n<p><strong>Researcher<\/strong>: Heena Kiritbhai Patel; <strong>PI<\/strong>: Anozie Ebigbo<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h3 class=\"wp-block-heading\">Project-related presentations:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Patel, H.
