A python library for identifying bubbles/droplets based on volume of fluid (VOF) simulation data.
It is suggested to install the library with Numba enabled:
pip install blobid[numba]
For the latest release: dgaylo.github.io/blobid-python
Here we load a 2D slice from a simulation of air bubbles in water near the surface, and then use this library to identify and label all the air bubble.
>>> import numpy as np
>>> from blobid import get_labels
>>> vof = 1.0 - np.load("tests/resources/fs_vof.npy")[:, 0, :]
>>> labels = get_labels(vof, periodic=[True, False])Below is a rendering of the vof field (air is white, water is black) and the labels field calculated using get_labels()
The full script, including creating these graphics using Matplotlib, is doc/example.py.
