Overview

• Primitive variable pipe flow code for incompressible flow.
• Double-Fourier (theta,z) + finite difference (r).
• PPE formulation; influence matrix corrects boundary conditions to machine precision.
• Second-order predictor-corrector method, automatic timestep control.
• Serial or parallel (with MPI).
• Fortran 90, uses modules and derived types, no esoteric extensions.
• Core program <3000 lines.
