This month in AvaFrame - April 2021 edition

Posted by OpenNHM on Wednesday, May 5, 2021

Welcome to the April 2021 edition of our monthly update.

Apart from the release of version 0.3, we put a lot of effort into our python/cython dense flow avalanche module com1DFAPy, targeting a swap with com1DFA within the next month:

  • com1DFAPy now includes:

    • an additional particle initialisation method: the per depth method

    • the option to use secondary release areas. They are being triggered if particles enter the area of a secondary release area.

    • split simulation types for entrainment and resistance. So far only a combined type existed. This allows for more granular and easier control of different simulation setups.

    • distinguish grid size used for the normal computation and for interpolating the fields from the grid used for neighbour search (kernel smoothing length).

    • an option to remesh the input DEM

    • better output options to reduce computational costs (mainly RAM usage)

    • proper handling of overlapping release areas

The second big block tackles reporting and visualisation:

  • output options for visualisation in Paraview

  • introduce constraining plots to data plus a buffer zone

  • generate report and plots to validate the entrainment

  • update benchmark files, ini files and run scripts to new options

  • improve Aimec plots (add some statistical information about the error)

And last but not least, this month also saw us also focusing on getting things ready for the EGU:

  • a new page was introduced in our docu about testing including an example of a full report of our standard tests. There you’ll also find all available test topographies.

  • we presented these tests and our strategy at EGU21, see abstract and publicly available video .
