What Kanapy is

Kanapy is a free Python package for generating three-dimensional synthetic polycrystalline microstructures from statistical grain and phase morphology data plus crystallographic texture information. It analyzes experimental EBSD maps, reconstructs crystallographic texture from measured orientations and misorientation distributions, and supports multiphase structures with explicitly defined matrix and dispersed phases. A hexahedral mesh generator represents complex microstructures as voxels for finite-element simulations. Kanapy can create spherical particle position and radius files for Neper, input files for Abaqus and other finite-element packages, and voxel structures exchanged through the modular materials data schema. Users access it through a Python API and command-line tools; the alpha-version GUI remains under development. Installation is documented through conda-forge or pip in a Python environment. Listed dependencies include NumPy, SciPy, Matplotlib, orix, NetworkX, and scikit-image. Texture functions additionally require MATLAB and MTEX installed separately. Linux, macOS, and Windows are supported; Linux and macOS require a working C/C++ compiler, while Windows uses a pre-built wheel. The project targets research and industry microstructure generation.

Who it suits

Kanapy suits researchers and engineers generating synthetic microstructures for finite-element simulations and related research or industry work. It fits users comfortable with Python, command-line tools, and the listed scientific dependencies.

What it does well

Supports explicitly defined matrix and dispersed phases
Exports files for Neper and Abaqus workflows
Provides Python API and command-line access

What to know first

Alpha GUI is still under development
Texture module requires MATLAB and MTEX separately
Linux and macOS require a C/C++ compiler
Depends on several scientific Python packages

Verdict

Kanapy provides an open package for statistically and experimentally informed microstructure generation, analysis, and meshing. Its integrations and platform support are useful, but setup involves scientific dependencies and compiler requirements.
