Operating system: Ultrix & OSF/1, HP/UX, AIX, NeXT-Step, IRIX, Sun.
RAM: 380K words

Keywords: Solid state physics, Other, Fluid dynamics, Hydrodynamic, Interactions, Colloidal Suspensions, Macromolecules, Low-Reynolds-number flow, Multipole expansion.
Classification: 7.7, 12.

Nature of problem:
Friction and mobility matrices for systems of equal spherical particles in colloidal suspensions, assuming low-Reynolds-number flow.

Solution method:
Construction of a linear system of equations for the force multipole moments induced on the particles by external forces and flow fields; solution of these equations with standard methods; addition of short- term corrections in pair approximation.

Unusual features:
The C preprocessor is used to provide global parameters and conditional compilation for the Fortran code. A set of Unix shell scripts limits recompilation of the source code to a minimum. Pure portable Fortran 77 code can be generated by another shell script.

Running time:
6.5 s/configuration for 10 particles using double-precision arithmetic on a DECstation 5000/260.
