There are a few types of grids/maps/files that are discussed below:
- A HOMME mesh: A HOMME mesh is either built in HOMME internally, based on Number of Elements (NE) per cube edge (so there is no file that HOMME reads), or an Exodus *.g mesh that lists conforming quadrilaterals. See Atmosphere Grids and the very first plot for an example of a HOMME uniform mesh (quadrilaterals are blue, quadrature points, or degrees of freedom, are green).
- A SCRIP file: A mesh that is required to couple HOMME to other parts of the model. It is a dual grid for the HOMME grid. It contains spherical polygons that are centered (in a general sense) at HOMME grid (quadrature) points. Its name usually contains suffix _scrip. See Atmosphere Grids for more information. Elaborate on _chevrons, _pentagons...
- A LATLON file: A file that contains latlon data of HOMME quadrature points/DOFs in a certain format. Its name usually contains suffix _latlon. See Atmosphere Grids for more information. This file is not needed to create domain files.
- An _aave file: A conservative mapping file from one SCRIP file to another with suffix _aave in its name. Needed to construct domain files.
- A _bilin file: A bilinear, not conservative, mapping file from one SCRIP file to another with suffix _bilin in its name.
- Domain files: Add to this.
