Nature of problem:
Computation of the bleaching of ground state atoms in 3-level atoms in a two-dimensional cylindrical cell, with inclusion of particle diffusion, and of nonlinear trapping in such a geometry. The program can be easily specialized to treat the simpler, more usual radiation trapping problems.
Monte Carlo treatment of trapping and analytical solution of the diffusion equation for the particle diffusion.
Restrictions of the achievable accuracy by memory and run-time limitations.
None (An external random number generator might be convient.)
Strongly dependent on the required accuracy; will be between 100 and 10000 CPU seconds in most practical cases.
