Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Tool Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 2D Spatial extent Regional-Scale Model domain Coastal, Marine One-line model description A graphical Matlab interface to the C language 2-D quality finite element grid generator Triangle. Extended model description BATTRI does the mesh editing, bathymetry incorporation and interpolation, provides the grid generation and refinement properties, prepares the input file to Triangle and visualizes and saves the created grid.

Model availability Source code availability (Or provide future intension) Through web repository Source web address http://www-nml.dartmouth.edu/Software/battri/ Source csdms web address Program license type Other Program license type other Memory requirements Typical run time Describe input parameters To generate a grid, the user should input the boundary node information, boundary segment information and hole (or island) information in form of a .poly file, as described in the Triangle manual (http://www.cs.cmu.edu/~quake/triangle.poly.html). These input nodes and segments in the .poly file are forced into the triangulation of the domain. Alternatively (and this is a strong point of BATTRI), all this information can be created from only a bathymetric dataset with the use of the editing options of BATTRI (see Option 0 in Running BATTRI section). This process may require manual deleting of unnecessary segments and nodes, closing of islands by segment adding, addition of an open ocean boundary segment, etc. As a starting point, ordered digital coastline node data can be extracted from the National Geophysical Data Center's webpage (https://www.ngdc.noaa.gov/mgg/shorelines/) at various scales ranging from 1:70,000 to 1:5,000,000. If the coastline is very highly resolved, causing an excessive number of elements along the shoreline, the routine "xy_simplify.m" can be used to reduce the number of nodes to the desired resolution. Remember to format this data into a .poly file, consisting of nodes and segments, before inputting into BATTRI. To refine an already created grid, the user can input the above referenced information either in the form of a previously created .poly file or in the form of NML standard .nod, .ele and .bat files (see next section, Running BATTRI).
