Welcome to the May 2025 update:

This month we took part in the INAC 2025 conference, including a talk on “New Normative and Digital Instruments in Avalanche Protection” which also had AvaFrame as a topic.

One of the biggest change this month is the switch away from conda to pixi for our development environment. The documentation has been updated accordingly.

The project ForestFrame 2 is coming to an end, we are currently working on the report. You can expect some changes regarding resistance areas in future releases.

Welcome to the March update:

Apart from the usual bug fixes and improvements, we changed one pain-point by adding mid-run persistence (e.g., saving progress/simDF) and resume capability for multi-simulation runs of com1DFA. This allows for restarts of simulations

Regarding shapefile polygons produced by AvaFrame: these are properly closed (endpoint equals startpoint) now, both for idealized release areas and when writing shp files

On the admin side, we replaced Code Climate and Codecov with qlty.sh, which is relevant for developers only.

Welcome to the first update of 2025:

Major work is being done of a change on our input side: we are including support for geotiff files. We will of course keep the asc format, but the geotiff format allows for a better integration and checks in relation to geographic information (i.e. coordinates, projections, etc.). Expect this to be released with a new version within the next weeks.

Work on the ISeeSnow paper is progressing nicely, as well as the work on our regional modelling project.

Welcome to the December 2024 update:

Related to ForrestFrame 2 we are looking into different treatment of resistance forces, experimenting with existing approaches and ideas. A lot of work is going into the report of the ISeeSnow project, which we aim to publish next year.

And this is basically a repeat from last month: the regional modelling project is also coming along nicely.
Current topics are the splitting of larger input areas and efficient handling during computation.

Welcome to the November 2024 update:

We released a new version this month, please head over to [Version 1.9](https://github. com/avaframe/AvaFrame/releases/tag/1.9) to see the details.

A new friction model is available, the spatialVoellmy friction model. It allows to read mu/xi values from a raster during initialization. We included this for our project ForestFrame 2, which investigates the handling of resistance areas, i.e. forests, in com1DFA. Expect a few more changes in the upcoming months related to the treatment of this.
