Welcome to the last update of this year.
|
||||
|
||||
Another new tool was added to AvaFrame: calculating glide snow avalanches using the
|
||||
*com1DFA* module. This required significant internal additions like a new particle
|
||||
initialization method, adding bonds between particles and some other numerical functions.
|
||||
This, and the documentation, will end up in the next release, which is coming soon.
|
||||
|
||||
We are also working on indicating within the simulation names of com1DFA whether the
|
||||
default parameters were used or something was changed. You'll also find this in the next
|
||||
release.
|
||||
|
||||
Apart from these topics, we finally submitted our first paper with all the gory details of
|
||||
our com1dfa theory. Let's see how this goes. And we are working on running multiple
|
||||
simulations in parallel, finally using all those bored CPU cores you got lying around.
|
||||
|
||||
With that, thanks for all the feedback we got this year; it is always appreciated!

Ok, so let this year begin!
|
||||
|
||||
This month's main thing was the release of version 1.4; please head over to the [release
|
||||
info](/posts/version1_4/) of *version 1.4* to read more about it.
|
||||
|
||||
Please note that we did not include an update to the AvaFrameConnector for QGis. We have
|
||||
bug reports of unexpected crashes on Windows, and we are trying to determine the cause.
|
||||
|
||||
The parallel computation is now included in the master branch and will end up in the next release.
|
||||
|
||||
And finally, the preprint of our com1DFA article is open for discussion, head over to
|
||||
[GMD](https://egusphere.copernicus.org/preprints/2023/egusphere-2022-1291/) for more
|
||||
information.
|
||||
|
||||
As always: if you run into problems or have ideas and feedback, don't hesitate to contact us!

Welcome to the November 2022 update.
|
||||
|
||||
This month brought a lot of internal improvements and fixes, apart from one topic:
|
||||
|
||||
The dense flow module *com1dfa* now contains the functionality of wall lines.
|
||||
These can be utilized to represent the effects of dams. However, please be aware of two things:
|
||||
|
||||
- first: this is untested and should only be used for experimental purposes.
|
||||
- second: the application is directional dams, not catching dams.
|
||||
|
||||
You can learn more about it in our [documentation](https://docs.avaframe.org/en/latest/theoryCom1DFA.html?highlight=dam#dam).
|
||||
|
||||
We also met with our operational team, collecting feedback and discussing
|
||||
current developments. You find some outcomes from that in our issues...
|
||||
|
||||
On to the next month,
