Overview
- Primitive-variable pipe-flow code for incompressible flow.
- Highly efficient, may be run serial or parallel (if MPI present).
- Readable Fortran 90, uses modules and derived types, no esoteric extensions.
- Core program <3000 lines.
- 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.
Aims
- To facilitate rapid entry into the world of numerical simulation and fluid dynamics.
- To provide flexible modules for more the use and development of advanced techniques in research.
Manual, Tutorial, FAQ
Please see the links on the left sidebar. The Manual covers setup, basic usage, definition of the model and conventions used in the code.
Database
The Database provides sample parameters and initial conditions from which to launch new simulations. In general, simulations start most reliably from an initial state computed for similar parameters. A range of starting points are provided.
