Abstract. OceanMesh2D is a set of user-friendly MATLAB functions with pre- and post-processing utilities to generate two-dimensional (2D) unstructured meshes for coastal ocean circulation models. These meshes are generated according to a variety of feature driven geometric and topo-bathymetric mesh size functions, which are controlled by user-defined parameters. Mesh generation is achieved through a force-balance algorithm to locate vertices and a number of topological improvement strategies aimed at improving the worst case triangle quality and adjusting the shoreline representation. The software embeds the mesh generation process into an object-orientated framework that facilitates rapid workflows on personal computers. These workflows are flexible, reproducible, and script-able. Through real world examples, we illustrate the various capabilities of the software and demonstrate how it can produce high-quality, multiscale, unstructured meshes that are faithful to a variety of constraints and automatically conform to arbitrary shoreline vector datasets. The objective of this paper is to describe the functionality of the software.

Short summary
Computer simulations can be used to reproduce the dynamics of the ocean near the coast. These simulations often use a mesh of triangles to represent the domain since they can be orientated and disparately sized in such a way to accurately fit the coastline shape. This paper describes a software package (OceanMesh2D V1.0) that has been developed in order to automatically, objectively, and reproducibly design triangular meshes based on input data that represent the coastline and ocean depths.
