ICE_IO
Reading and Writing ICE Datasets in NETCDF Files

ICE_IO is a directory of MATLAB programs which read or write ICE dataset, which define a 3D grid, using the NETCDF file format.

Languages:

ICE_IO is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version.

Related Programs:

ICE, a data directory which contains examples of ICE files, which store icesheet grid datasets in the NETCDF format.

ICE_TO_MESH, a MATLAB program which reads a NETCDF file containing an ICE dataset and rewrites the information as a MESH file.

MESH, a data directory which contains examples of MESH files, which can be used to define the geometry of a finite element mesh in 2D or 3D, using triangles, quadrilaterals, tetrahedrons or hexahedrons.

Source Code:

• ch_cap.m returns the capitalized version of a character;
• cyl248.m, defines the data associated with a 3D tetrahedral mesh;
• hexahexa_2x2x2.m defines a 3D hexahedral grid.
• ice_iprint.m prints an ICE dataset.
• ice_read.m, reads an ICE dataset from a NETCDF file.
• ice_write.m, writes an ICE dataset to a NETCDF file.
• s_eqi.m, is TRUE if two strings are equal, ignoring case and trailing blanks;
• timestamp.m, writes the YMDHMS date as a timestamp.

Examples and Tests:

• ice_io_test.m, runs all the tests;
• ice_io_test_output.txt, the output file;
• ice_io_test01.m, calls ICE_WRITE to write a mesh to a NETCDF file;
• ice_io_test02.m, calls ICE_READ to read a NETCDF file;
• hexahexa_2x2x2.nc, a hexahedral mesh written and read by the tests.
• cyl248.nc, a tetrahedral mesh written and read by the tests.
