Version 3.0 marks a milestone release for Φ-Flow, introducing many new features and simplifying the API.
Highlights
Support for unstructured meshes. This includes many field and physics operations, allowing grid simulations to be ported to FVM with little effort. Meshes can be loaded from .su2 and .gmsh files.
Major plotting improvements: new plot types, such as bar charts, histograms, streamlines, points clouds with cmap. More flexible arguments, e.g. error bars, color, alpha, same_scale.
Improved documentation: The GitHub page now lists a collection of examples in the form of Jupyter notebooks.
Sparse neighborhood search using GPU-enabled hash grids. This enables simulations with interacting particles, such as SPH.
All linear solves can now use the ILU preconditioner.
The phi.math package is now stand-along as the phiml library.
All types of fields have been merge into the Field class which makes a lot of functionality more easily accessible. The legacy constructors still work but now return Field instances.
Boundaries are now easier to define, e.g. {'x-': 0, 'x+': 1}
