The facts
Each one read from blobmodel's own pages, with the date it was checked.
What it does
- 3D visuals
- Nochecked 23 Sep 2026
- Authoring tools
- Yeschecked 23 Sep 2026
- Blob shapes
- Supported shape choices include exponential, Lorentz, double exponential, Gaussian, secant, dipole, and rectangular.checked 12 Oct 2026
- Custom parameters
- Users can implement a custom BlobFactory to define blob parameters individually; they are responsible for ensuring variables have correct dimensions and manually normalizing parameters if needed.checked 11 Oct 2026
- Data export
- Yeschecked 23 Sep 2026
- Installation
- The documentation provides installation from PyPI with `pip install blobmodel`.checked 12 Oct 2026
- Intended research
- The project was originally developed to study the scrape-off layer of fusion experiments and may apply to other one- or two-dimensional systems.checked 12 Oct 2026
- Label output
- Users can add same-region or per-blob integer labels to the output dataset, which the documentation notes may help create supervised machine-learning training data.checked 12 Oct 2026
- Model setup
- A model lets users specify grid dimensions, domain lengths, time step, time length, initial time, blob shape, drainage time, and blob count.checked 12 Oct 2026
- One-dimensional mode
- Setting `one_dimensional` to true discards the perpendicular blob shape and sets `Ny=1` and `Ly=0`.checked 12 Oct 2026
- Open source
- The documentation describes blobmodel as an open source project developed by the Complex Systems Modelling group at UiT The Arctic University of Norway.checked 11 Oct 2026
- Output
- A realization is returned as an xarray dataset and can be saved locally by passing a filename to `make_realization`.checked 12 Oct 2026
- Parameter distributions
- The default factory supports distributions for blob amplitudes, widths, velocities, pulse shapes, alignment, and tilt, and users can implement a custom factory.checked 12 Oct 2026
- Periodic boundary behavior
- With `periodic_y` enabled, blobs leaving the domain in the y direction enter at the opposite end; the docs caution that the y domain should be large compared with blob widths.checked 11 Oct 2026
- Periodic boundary caveat
- The documentation advises using y-periodicity only when the y-domain is large compared with blob widths and says the code warns when a blob width is less than `0.1 * Ly`.checked 12 Oct 2026
- Purpose
- blobmodel is a Python package for creating numerical realizations of advecting and dissipating blobs in up to two spatial dimensions.checked 12 Oct 2026
- Support and contribution
- The project invites users to report bugs or request features on GitHub and contribute pull requests.checked 12 Oct 2026
- Visualization
- The package provides `show_model` to plot a model realization as an animation.checked 12 Oct 2026
Money
- Free plan
- Yeschecked 23 Sep 2026
Where it runs
- Machine learning use
- The optional blob_labels field can label occupied regions or individual blobs, and the documentation says it can be useful for supervised machine learning training datasets.checked 11 Oct 2026
