Overview of the solver
- File:TheOpenpipeflowSolver.pdf an overview document. How to cite openpipeflow.org...
Using the simulation code:
- Getting started - overview of files, setup, starting and ending a job.
- Tutorial - setup a job, basic monitoring and visualisation of outputs.
- Core implementation - discretisation, timestepping and key programming elements.
- Parallel i/o - a brief note on parallel data access.
- Utilities - pre/post-processing, runtime processing and manipulations, non-problem specific codes.
Non-problem specific codes
- The are designed for integration with any pre-existing code.
- arnoldi.f - Krylov-subspace method for calculating eigenvalues of a matrix.
- GMRESm.f90 - Krylov-subspace method for solving the linear system Ax=b for x.
- NewtonHook.f90 - Newton-hookstep method.
Equations, properties, methods, etc.:
- Equations and parameters - Non-dimensionalisation, Navier-Stokes, Reynolds numbers.
- Differential operators in cylindrical coordinates - grad, div, curl, Laplacian, etc.
- Symmetries of pipe flow - discrete and continuous symmetries.
- Method of slices - symmetry reduction, elimination of physically irrelevant spatial shifts.
- Newton-Krylov-Hookstep (channelflow.org) - details of the Newton-Krylov method.
