threedigrid-builder 0.1.1

Generate a 3Di simulation grid from a model schematisation.

threedigrid-builder

Generate a 3Di simulation grid from a model schematisation.

Installation

This package is distributed as binary only, because its (Fortran) source code is proprietary. The only currently supported platform is Linux.

First install sqlite and spatialite libraries, e.g. on Ubuntu:

$ sudo apt-get install sqlite3 libsqlite3-mod-spatialite

Then install the threedigrid-builder:

$ pip install threedigrid-builder

For output into a file for the 3Di calculationcore, enable gridadmin output:

$ pip install threedigrid-builder[gridadmin]

For output into Geopackage for display in e.g. QGis, enable gpkg output:

$ pip install threedigrid-builder[gpkg]

Usage

The public API of threedigrid_builder can be found in threedigrid_builder.application.

Changelog of threedigrid-builder

0.1.1 (2021-04-20)

• Fixed automatic PyPI upload.

0.1.0 (2021-04-20)

• Partially ported functionality from inpy (generate 3di files, makegrid): 1D channel grid (including calculation_type and bottom_level), and 2D open water grid.

• Added gridadmin and geopackage output.

• Breaking change: the interpolation between cross section locations (channels) now also extrapolates for lines and nodes that are not in between two connection nodes. This happens only if the channel has at least 2 cross section locations. When extrapolatic, the line.cross_weight is less than 0 or greater than 1.

• Breaking change: missing or empty values in float datasets in the output gridadmin are now denoted by NaN (not-a-number) instead of -9999.0.

• Breaking change: integers in the output gridadmin are now always 32-bit (instead of sometimes 32-bit and sometimes 64-bit).
