You can learn more about it in our documentation .

The main thing this month was the release of version 1.3, please head over to the release info of version 1.3 to read more about it.

This meant a lot of work went into bug squashing, removal of minor niggles and improvement of the documentation.

Please be aware that the installation method for QGis changed significantly. The AvaFrameConnector now tries to install the python package automatically. Hopefully this makes is a bit easier to get started. We also provide an update function in the AvaFrameConnector.

Today we released Version 1.3

The main change is the change of logic for secondary release areas. This was done to be able to expose these functions in the AvaFrameConnecter. So it is now possible to include secondary release areas in dense flow simulations done via QGis. Please also make sure you read the new installation instructions .

ENHANCEMENTS

• Change logic for secondary release areas:
  • Check for release and secondary release shapefiles
  • If only release available -> just run release
  • If both release and secondary release are available -> run with secondary release UNLESS secRelArea = False
  • ALL scenarios in release get the secondary release areas!
• Add rotational energy line test: helps to check eg. for numerical grid independence
• Update ini file procedure for the energy line test and the rotation test
• Additional statistical plots
• New three-panel plot of tt-diagram (plus animation)
• Add variation option for thickness settings and probrun based on normal distribution derived from ci and mean
• Add filtering option to aimec
• Add scenario name to configuration to be used for plotting example #757
• Add surface parallel coordinate computation to Aimec
• Improve operational installation instructions
• Add a german version of the operational installation

FIX

This was the month of conferences: First was the International Mountain Conference on our door steps in Innsbruck. We had a session about Gravitational mass flow simulations for avalanches with a bunch of very interesting talks. Thanks again to everyone who contributed and visited. The program can be found here .

We also took this opportunity to hold the Scientific Meeting, discussing, among other things, the future direction AvaFrame takes. We cannot share details yet, but we are excited!

Today we released Version 1.2

The main changes are the automatic split point generation and optional computation of fields inside the calculation loop. Furthermore, renaming functions used for the QGis AvaFrameconnector are included.

ENHANCEMENTS

• Add function for renaming simulations, i.e. adding info to the simName. Used for AvaFrameConnector
• Split cfgUtils: Utils contain all reading and writing; cfghandling has functions that do something with the cfgInfos
• Make computation of ppr, pta, P, TA and pke optional within the calculation loop. Only compute them if they are required as output
• Add automatic split point generation: - First run a DFA simulation, either using the runDFAModule flag in runComputeDFAPath.py or yourself
  • Do not forget that you need to save particles or FD, FM, FV for multiple time steps
  • What DFA parameters to use is not yet clear. I would use the BenMoussa time stepping and particles parameters, sphOption 2, explicit friction option 1, some artificial viscosity, and maybe activate curvature (with all this and a mu=0.42, I get ok results)
  • Then runComputeDFAPath computes the mass average path, extends it and defines a splitPoint

FIX

To know what went on, head over to the release info of version 1.2.

So we recommend you update your installations, you will find the instructions at our documentation at the end of the installation instructions .
