The Center for Coastal and Land-Margin Research is an academic research center of the Oregon Graduate Institute of Science and Technology (OGI). The Center consists of scientists from different institutions in the United States and Canada, around a core of faculty of OGI's Department of Environmental Science and Engineering.
The focus of the Center is on regional-scale, interdisciplinary research and its applications in ecosystems at the margins of the land and the sea: coasts, coastal embayments, estuaries, rivers, wetlands, and watersheds.
Advanced modeling and scientific visualization techniques are used as a framework to connect, assess, and enhance process-oriented research in physics, chemistry, and biology of land-margin ecosystems.
An introduction to ACE/gredit: what it is and what it does
ACE/gredit is a tool for the flexible, interactive, semi-automatic generation of two-dimensional triangular finite element grids. Although designed to support studies of estuarine and coastal dynamics and water quality, ACE/gredit can be perceived as a rather generic tool, with wide application.
A typical grid is built based on a domain outline (a shoreline, for estuarine/coastal applications) and an unstructured set of points, each associated with a fundamental property of the domain (the water depth, in estuarine/coastal applications). The user retains full control of the grid design, while letting the computer perform the mechanical, time-consuming tasks. A menu-driven interface makes the use of ACE/gredit fairly intuitive and self-explanatory.
We note that ACE/gredit targets the generation of geometrically complex but static grids; self-adaptive grids in time are not handled by this software.
ACE/gredit: Hardware and software requirements
ACE/gredit is designed for workstations and X-terminals operating under UNIX and the X window system with the Motif graphical user interface. ACE/gredit has also been ported to Windows 95/NT using Hummingbird Corp's Motif toolkit.
