A numerical solution to the steady-state equation of transfer in azimuthally symmetric geometries

The code GLAM solves the two-dimensional, azimuthally symmetric, steady-state equation of transfer for the energy density, flux and pressure tensor. The code calculates the intensity along a given pay and then numerically integrates the intensity to obtain the various moments. A unique feature of the code is the method for the calculation of the limits of the azimuthal angle. The code can handle the source-free vacuum equations and problems with emission and isotropic scattering sources. The code also has an option for the calculation of geometric view factors.
