First run

Follow these steps to run your first simulation (assuming you finished the complex usage installation steps). The commands below use pixi run, so you do not need to activate the environment via pixi shell first:

  • change into your AvaFrame directory (replace [YOURDIR] with your path from the installation steps):

    cd [YOURDIR]/AvaFrame/avaframe

  • run:

    pixi run python runCom1DFA.py

  • a similar output should show up:

    logUtils - INFO -  Started logging at: 03.11.2020 22:42:04
logUtils - INFO -  Also logging to: data/avaParabola/runCom1DFA.log
runCom1DFA - INFO -  MAIN SCRIPT
runCom1DFA - INFO -  Current avalanche: data/avaParabola
...

This will perform a dense flow avalanche simulation using the com1DFA module. The results are saved to data/avaParabola/Outputs/com1DFA. For a first look at the results, got to the folder reports, there you can find a markdown report of the simulations performed including some plots of the results.

To display markdown files in a nice way use a markdown viewer of your choice. Some other options are:

  • Use the Atom editor with a markdown plugin

  • If you have pandoc installed use this to convert it to pdf/html

  • Some browsers have markdown extensions you can install easily

Workflow example

The following example should make it easier for you to find your way in AvaFrame and setup your own AvaFrame workflow after you did the full setup. There is also a directory with examples for different workflows, see more here: Example runscripts.

Make sure you change to your AvaFrame directory by:

cd [YOURDIR]/AvaFrame

Replace [YOURDIR] with the directory from your installation step.

Initialize project

To create the folder where the input data lies and where the output results will be saved, specify the full path to the folder in the local_avaframeCfg.ini (which is a copy of avaframeCfg.ini that you need to create). So:

cd avaframe
cp avaframeCfg.ini local_avaframeCfg.ini

and edit local_avaframeCfg.ini with your favorite text editor and adjust the variable avalancheDir.

Then run

pixi run python runScripts/runInitializeProject.py

This will create a new directory with the input required by AvaFrame structured as described in Initialize Project.

Input data

Check the input data required by the different modules you want to use and fill the Inputs/ inside the [avalancheDir] folder from the initialize step accordingly.

For example the com1DFA module needs input as described in Input. You can also have a look at the default setting for the module you want to use (for example com1DFACfg.ini for module com1DFA). If you want to use different settings, create a local_ copy of the .ini file and modify the desired parameters.

More information about the configuration can be found here: Configuration

Building your run script

Create your own workflow by taking the runOperational.py script as template.

We suggest you copy it and adjust it to your liking. There are annotations in the code that should help you to understand the structure.

A lot more examples can be found in the runScripts directory (see also Example runscripts).
