Nature of problem:
This code calculates the transport of neutral particles in thermonuclear plasmas in two-dimensional geometric configurations.
The code is based on the Transmission and Escape Probability (TEP) methodology , which is part of the family of integral transport methods for neutral particles and neutrons. The resulting linear system of equations is solved by standard direct linear system solvers (sparse and non-sparse versions are included).
The current version of the code can handle only one species of atomic neutrals.
The program requires linking with the publicly available LAPACK linear algebra library which is usually included with the Fortran compilers of many UNIX vendors or can be obtained from NETLIB (www.netlib.org). To use the optional sparse matrix solver, the UMFPACK library is required which can be obtained from www.cise.ufl.edu/research/sparse/umfpack
It depends on the size of the problem and the computing platform. For example, it takes 15.6 seconds of user time to run the second test problem on a SUN Ultra 10 workstation, using the sparse linear matrix solver.
