We released AvaFrame Version 2.1 (full changelog)
This release focuses on stability fixes in com1DFA, major changes to the com9MoTVoellmy build pipeline, and new output features across com4FlowPy and com6RockAvalanche.
Key changes:
-
com9MoTVoellmy build-on-release: The C binary is now compiled at release time (or on demand) instead of shipping precompiled binaries. Source is fetched automatically from the latest upstream MoT-Voellmy release. This release includes MoT-Voellmy v2026-05-04 , which fixes a bug in the AvaFrame-entrainment model (entrainment energy now correctly read from file).
-
com1DFA fixes and features: A long-standing memory corruption bug affecting com5SnowSlide is fixed — arrays returned by
updateFieldsCare now properly owned copies. Particle property saving is now selective: you can configure which properties to save, reducing output file sizes. Time-dependent release handling now supports multiple files for parallel simulations and more release features. -
com4FlowPy output improvements: Computes
startCellIDper cell and generates output polygons for each process path. -
com6RockAvalanche fixes:
scarp.pyno longer produces negative values in raster output. The config file (com6RockAvalancheCfg.ini) now exposes all adjustable parameters. -
in2Trans raster-to-NetCDF: New
rasterUtilsfunctions to convert rasters to NetCDF files. -
Documentation updates: Time-stepping configuration in com1DFA is now clearer (fixes #1285 ). An AI/LLM usage section has been added to the developer guide.
