Checks validity of a threedi-model
Project description
Threedi-modelchecker is a tool to verify the correctness of a 3Di schematisation. The goal is to provide a tool for builders to quickly check if his/her schematisation is correct and can be converted to a 3Di-Model to run a 3Di simulation. It provides detailed information about any potential errors in the schematisation.
Threedi-modelchecks only work against the latest 3Di migration: https://docs.3di.lizard.net/en/stable/d_before_you_begin.html#database-overview
Note:
In 2021 we changed the naming within the 3Di realm. To better understand what users meant with ‘model’ we made a clear distinction between a schematisation and a model. A schematisation is build interactively by the user and this schematisation will be converted to a 3Di-Model which can be used in simulations. This repo is still called the threedi-modelchecker which might lead to confusion.
Installation:
pip install threedi-modelchecker
Threedi-modelchecker is also integrated into the ThreediToolbox Qgis plugin: https://github.com/nens/ThreeDiToolbox
Example
The following code sample shows how you can use the modelchecker to run all configured checks and print an overview of all discovered errors:
from threedi_modelchecker.exporters import format_check_results
from threedi_modelchecker import ThreediModelChecker
from threedi_modelchecker import ThreediDatabase
sqlite_file = "<Path to your sqlite file>"
database = ThreediDatabase(sqlite_file)
model_checker = ThreediModelChecker(database)
for check, error in model_checker.errors(level="WARNING"):
print(format_check_results(check, error))
Command-line interface
Use the modelchecker from the command line as follows:
threedi_modelchecker -s path/to/model.sqlite check -l warning
By default, WARNING and INFO checks are ignored.
Migrations
Migrate the schematisation file to the latest version as follows:
threedi_modelchecker -s path/to/model.sqlite migrate
The file will be change in-place.
Development
A docker image has been created for easy development. It contains an postgis server with an empty 3Di database to allow for easy testing.
Build the image:
docker-compose build
Run the tests:
docker-compose run modelchecker pytest
See Creating revisions for instructions on how to change the 3Di model schematisation.
