  A Python package for post-processing of plane two-dimensional data from
computational fluid dynamics simulations is presented. The package, called
turbulucid, provides means for scripted, reproducible analysis of large
simulation campaigns and includes routines for both data extraction and
visualization. For the former, the Visualization Toolkit (VTK) is used,
allowing for post-processing of simulations performed on unstructured meshes.
For visualization, several matplotlib-based functions for creating highly
customizable, publication-quality plots are provided. To demonstrate
turbulucid's functionality it is here applied to post-processing a simulation
of a flow over a backward-facing step. The implementation and architecture of
the package are also discussed, as well as its reuse potential.
