Nature of problem:
Modeling and simulation of two-dimensional multiple wave scattering by large clusters of circular cylinders for any frequency. The program is well-designed to manage highly accurate solutions for deterministic or random media, with various boundary conditions and physics properties of the scatterers. Pre- and post-processing facilities are designed specifically for these problems.

Solution method:
We use spectral Fourier approximation schemes and direct or iterative Krylov subspace methods.

Running time:
From a few seconds for simple problems to a few minutes for more complex situations on a medium computer.
