MESH_IO
Reading and Writing MESH Files

MESH_IO is a directory of MATLAB programs which read or write MESH files, which define a finite element mesh.

Languages:

MESH_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:

FEM_TO_MESH, a MATLAB program which reads a pair of FEM files defining node coordinates and elements, and creates a corresponding MESH file.

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.

MESH_TO_ICE, a MATLAB program which reads the ICE dataset information from a MESH files and rewrites it to a NETCDF file.

Source Code:

• ch_cap.m returns the capitalized version of a character;
• ch_eqi.m returns TRUE if a two characters are equal (ignoring case);
• cyl248.m, defines the data associated with a 3D tetrahedral mesh;
• hexahexa2x2x2.m, defines the data associated with a 3D hexahedral mesh;
• mesh_data_print.m, prints mesh data.
• mesh_read.m, reads mesh data from a MESH file.
• mesh_size_print.m, prints mesh sizes from a MESH file.
• mesh_size_read.m, reads mesh sizes from a MESH file.
• mesh_write.m, writes mesh data to a MESH file.
• s_begin.m, is TRUE if two strings match, up to the end of the shorter string, ignoring spaces and capitalization;
• s_eqi.m, is TRUE if two strings are equal, ignoring case and trailing blanks;
• s_len_trim.m returns the length of a string to the last nonblank;
• timestamp.m, writes the YMDHMS date as a timestamp.

Examples and Tests:

• mesh_io_test.m, runs all the tests;
• mesh_io_test_output.txt, the output file;
• mesh_io_test01.m, calls MESH_WRITE to write a hexahedral mesh;
• mesh_io_test02.m, calls MESH_WRITE to write a tetrahedral mesh;
• mesh_io_test03.m, calls MESH_SIZE_READ to read mesh sizes;
• mesh_io_test04.m, calls MESH_READ to read a mesh;
• hexahexa_2x2x2.mesh, the hexahedral mesh.
• cyl248.mesh, the tetrahedral mesh.
