How-to guides

Task-focused recipes. Read any of these independently — each solves one specific problem. They assume you’ve worked through at least the first tutorial. All examples run against the damBreak case shipped at examples/damBreak/; pyOFTools.clone_example() copies it to a tmp directory, then each script runs Allrun to generate the mesh and initialise the alpha field before driving the workflow.

Prerequisites:

• OpenFOAM v2406+ sourced.

• blockMesh and pyoftools on PATH (the latter is the pyOFTools CLI, installed with the package).

• pybFoam and pyOFTools installed.
