# This month in AvaFrame - January 2022 edition

## February 5, 2022

Welcome to the January 2022 update.

Our focus this month was the preparation for our upcoming version 1.0 release. We finished the month by publishing the first release candidate. See github releases for a full changelog.

- For the final release of version 1.0 we worked on a difference report, investigating our numerics and comparing it to com1DFAOrig.

- We streamlined and improved the way release thickness is being set in the DFA module com1DFA

  - it is possible now to add variations if release thickness is read from shapefile.
  - add percent and range variation options.

- A new probability runscript is now in its final development stages.

- On the numerics side convergence of com1DFA for the similarity solution test case was the topic of the month.

  - The aim is to extract a criterion between the time and space discretization parameters that leads to convergence of the numerical method towards the solution of the depth integrated equations.
  - We are now trying to do the same analysis on more test cases. Starting with idealized topographies and coulomb friction, but also real topographies.

- Further minor improvements here and there, including:

  - cleaning up runscripts.
  - cleaning benchmarks.
  - explore plotting options for uncertainty visualisation.

That’s it for this month, have a good start into this year!
