TET_MESH_VOLUMES is a C++ program which computes the volume of every tetrahedron in a tet mesh.
tet_mesh_volume prefixwhere prefix is the common file prefix:
The element definition file will list node indices. In C++, it may be more natural to use 0-based indices. This program will accept an element definition file that is 0-based or 1-based, and will convert a 1-based input file so that it becomes 0-based internal to the program. The detection of 1-based data is determined by the absence of the use of a 0 index, and the use of an index equal to the number of nodes. This is an implicit and fallible, but reasonable, way to handle this problem.
TET_MESH_VOLUMES is available in a C++ version and a FORTRAN90 version and a MATLAB version.
