This major release introduces several new features, model enhancements, and performance improvements. Key highlights include:

• The morphological acceleration factor (MORFAC) approach in BASEHPC for speeding up morphodynamic simulations

• Coriolis force momentum source term

• Massive extension and enhancement of the suspended load module in both BASEHPC and BASEchain (1D)

• The surface reconstruction method (SRM) combined with implicit frictional term treatment for solving hydrodynamic flux in extremely shallow conditions (e.g., surface run-off).

• Improved the performance of models with nodestrings and removed the limit of 200 nodes per nodestring

• New inner boundary type for BASEchain (1D) that computes discharge from a prescribed H-Q relation.

This version also includes extensive bug fixes, hence we recommend all users to update their program as well as the user manual to version 4.3. We kindly ask you to test your models with this version and give feedback if the program exhibits unexpected behavior. The changes compared to previous versions can be viewed at the following link: https://basement.ethz.ch/download/softw … -3-0.html/

We are pleased to announce the release of BASEmesh 2.3.1. This is a small bugfix release for the QGIS plugin:

• Fixed a crash when generating a quality mesh from a marker layer with empty (NULL) values in the MaxArea, MATID, or Hole fields.

Installation

The plugin is available in the BASEmesh plugin repository. Alternatively, you can download the archive from the release page and install it manually using the "Install from ZIP" option in the QGIS Plugin Manager. The Python package is available on PyPI:

pip install basemesh==2.3.1

Problems upgrading or uninstalling the plugin?

Upgrading, downgrading, or uninstalling the plugin from within QGIS can fail with the error messages "Plugin installation failed: Failed to unzip the plugin package" or "Plugin uninstall failed: Failed to remove the directory". This happens because QGIS keeps the plugin's compiled extension loaded while BASEmesh is enabled, so the plugin files cannot be replaced or removed. If you encounter this problem, please proceed as follows:

1. Open Plugins > Manage and Install Plugins > Installed and untick BASEmesh.

2. Close QGIS completely and start it again.

3. Upgrade, downgrade, or uninstall BASEmesh as usual.

4. If you uninstalled the plugin, re-enable it after reinstalling.

As a last resort, close QGIS and delete the basemesh_v2 folder in the python/plugins directory of your QGIS profile, then reinstall the plugin.

The full release notes are available on the release page. If you run into any other issues, please report them here in the forum.

The BASEmesh development team

We are pleased to announce the release of BASEmesh version 2.3.0. You can install and upgrade to the new version directly using pip or ifyou use QGIS plugin, simply upgrade in plugin manager.

Key Changes:
- The new version performs large meshing and cleaning up drastically faster than before (~1 sec run time now for a previously ~1 hour task).
- Elevation looking up from a mesh is also much faster now (~12x faster)
- Fixed nodestring ordering for bent or zigzagging line strings, which could previously result in incorrectly ordered nodestrings.
- Breaking change for Python users: the deprecated basemesh.basechange import path is gone. Use import basechange instead.

For QGIS Plugin users:
- The progress bars now work normally and show what's happening;
- Fixed a bug where some valid elevation mesh layers didn't show up in the Advanced Interpolation tab;
- Linux builds of the plugin now include the same compiled speed-up as Windows.

Other changes:
- BASEchange: fixed the last cross-section of a CSV/tabulated channel not picking up the template's default values, unlike every other cross-section in the channel.

This major release introduces several new features, model enhancements, and performance improvements. Key highlights include the LAGRANGIAN module in BASEHPC for simulating the transport of particulate substances using particle tracking, the MASSMOVEMENT module for simulating tsunamis generated by subaqueous landslides, and hydraulic boundary conditions for wave generation.

Since this version also includes some bug fixes, we recommend all users to update their program as well as the user manual to version 4.2. We kindly ask you to test your models with this version and give feedback if the program exhibits unexpected behavior. Changes compared to previous versions can be tracked in the Release Notes 4.2.

We are pleased to announce the release of BASEMENT version 4.0.

A full 20 years after the start of the project, we are proud to present version 4 of BASEMENT. This new major version is similar to the very first version of BASEMENT – released in 2006 – which consisted of the two modules BASEchain and BASEplane and had a modular workflow.
Version 4 also consists of two modules: BASEMD and BASEHPC. MD stands for “Multi-Domain” and corresponds to the previous version 2.8.2, HPC stands for “High-Performance Computing” and corresponds to the previous version 3.2. Thus, all features from the two previous versions are retained and integrated into a common simulation workflow.

We kindly ask you to test your models with this version, and give feedback if the program exhibits unexpected behavior. Changes compared to previous versions can be tracked in the release notes. Please refer to the documentation, part "Introduction and Installation", for more details about version 4.0. The Summary of Features provides an overview of the available functionalities of BASEMENT version 4.0, while the Migration Guide provides help with migrating existing simulations from previous versions 2.x and 3.x to version 4.0.

The newest version of the software system BASEMENT is available for free on our website.

We are pleased to announce the release of BASEmesh version 2.0 and BASEMENT version 3.1.0.

In BASEMENT Version 3.1.0 the bedload transport of uniform sediment has been extensively revised and supplemented (e.g. slope collapse). The new features include the transport of passive scalars and additional output variables (e.g. transport capacity or dimensionless bed shear stress). In general, extensive bug fixes were made and the documentation was revised. Since this version also includes some bug fixes, we recommend all users to update their program as well as the user manual to version 3.1. We kindly ask you to test your models with this version and give feedback if the program exhibits unexpected behavior. Changes compared to previous versions can be tracked in the release notes.

BASEmesh Version 2.0 has been completely rewritten to take advantage of new features in QGIS, such as the native mesh layer type and native 3D geometries. This redesign addresses a number of longstanding performance issues inherent in the previous implementation, especially regarding performance scaling for large projects. BASEmesh 2.0 is both a stand-alone python software as well as a plugin für QGIS. Detailed information such as release notes, a migration guide for version 2.0 and a user manual for most recent version are provided on the wiki of the BASEmesh repository.
