# This month in AvaFrame - May 2021 edition

## June 5, 2021

Welcome to the May 2021 edition of our monthly update. Our main goal was the preparation for the switch of the dense flow model com1DFA from a C code to python (cython) code. This meant to check every little detail and difference that we found as well as:

- updated the documentation for the new python com1DFAP: algorithm, workflow and description

- updated the re-projection method of particles. Now particles are re-projected normal to the surface and not vertically. This is especially important at sharp drops. We also added a test case for this.

- restructured the com1DFA run workflow

  - now everything is controlled in model configuration via ini (the previous com1DFA had a lot of internal setup)

  - allow for parameter variation runs right from python

  - new naming of simulations which provides easy filtering options

- restructured the benchmark workflow and updated run scripts for standard tests

  - added simple functions to fetch benchmarks

  - simplify plotting and AIMEC path functions according to new structure based on simulation name and configuration

- com2AB (Alpha Beta) now allows for running with custom parameters

- added an export function to visualise particle properties with Paraview

- started the development of the QGis Connection. See this repository for the development.

Since we are now nearing the milestone of our first public prototype, I guess we will have to start posting some nice graphics as well… So watch this space for upcoming posts! :-)
