Install ACTINV
Choose the desktop for a graphical workflow, or install the CLI and Python package for scripts and notebooks. Nuclear data are installed separately.
Desktop
Open the ACTINV download page and choose the package for your computer. No Rust or Python installation is required.
| Computer | Package | First launch |
|---|---|---|
| Windows, Intel or AMD 64-bit | Installer or portable ZIP | Install and open ACTINV from Start; for the ZIP, extract it and open ACTINV.exe |
| Mac, Apple Silicon | Apple Silicon disk image | Open the DMG and drag ACTINV to Applications |
| Mac, Intel | Intel disk image | Open the DMG and drag ACTINV to Applications |
| Linux, Intel or AMD 64-bit | AppImage | Allow execution in file properties, then double-click |
The published 0.1.0-preview.1 desktop is unsigned and uses solver 1.0.1. The CLI/Python software release is 1.3.1; features added afterward require a newer desktop build or the current CLI/Python package. Download filenames identify the desktop version and architecture.
For platform launch notices and the optional Linux application-menu shortcut, see the desktop installation details. Use the desktop walkthrough for calculation setup.
CLI and Python
On Python 3.9 or newer, install both import actinv and the actinv terminal command:
python -m pip install actinv
actinv --version
Supported platforms have prebuilt wheels. If a matching wheel is unavailable, pip may attempt a source build; use a standalone executable if you want to avoid setting up a compiler.
For a reproducible installation of this handbook’s software version:
python -m pip install actinv==1.3.1
If you already use Rust, install just the CLI from crates.io:
cargo install --locked actinv-cli --version 1.3.1
The Python package and cargo install actinv-cli install the terminal interface. Get the desktop from the download page.
Install the nuclear data
Choose a working folder for your problems and run:
actinv data fetch
actinv data verify
The default neutron bundle downloads about 79 MiB and installs about 170 MiB in actinv-data/v1.1.0/ inside that folder. The first calculation creates a separate prepared-data cache. Data setup explains custom locations, other particles, covariance bundles, and offline installation.
Continue with Your first calculation.
