Version 4.0.1

General

• Log and error messages during setup, simulation and results steps of the workflow are now written to a file.
• The latest GPU architectures Ada and Hopper should now be supported, but have not been explicitly tested. An upgrade to the latest NVIDIA driver might be necessary.

Known Issues

• Visualization of results in QGIS requires manual modification of .xdmf file: change '<Xdmf Version="3.0">' to '<Xdmf Version="2.0">'.
• Model setup fails if there is a dot ‘.’ in the working directory path. For example: “MySimulations/Sim1.1/" does not work, while “MySimulations/Sim1_1/” works.
• Aborting a simulation using Ctrl+C can corrupt the HDF5 result file.
• Tool tip text is too long to be displayed completely.
• Abort bottom may no work as intended, i.e. simulation does not stop.

Module BASEHPC

Bug fixes

• A bug during writing the .xdmf output file resulted in unresponsive behaviour when visualizing the results in ParaView or even errors in QGIS. This bug has been fixed for visualizing the results in ParaView. Since the QGIS mesh layer does not yet support XDMF Version 3.0 it is necessary to manual replace the line '<Xdmf Version="3.0">' at the top of the .xdmf output file by <Xdmf Version="2.0"> in order to load the simulation results onto the mesh layer.

Module BASEMD

Bug fixes - General

• A bug in the initialization of several model parameters (e.g. theta_critical, theta_critical_approach, etc.) resulted in BASEMD simulations to crash or not respond. Those parameters were previously intialized in the background if not explicitly defined by the user. The tags of those parameters are now mandatory in the model.json and are initialized with default parameters. The use of the default parameters results in the same behaviour as not explicitly specifying them in BASEMENT version 2.8.2 and earlier.

Known Issues - BASEplane

• The upstream and downstream stringdefs of the inner boundary weir must be of the same length, otherwise mass might not be conserved.

Known Issues - BASEchain

• Fixed bed starts eroding if both suspended load and bed load transport are activated if the suspended load is below transport capacity.
• Van Rijn formula does not result in any sediment being transported (1D-model).

Note: Existing installations of BASEMENT version 3.0.1 (or earlier) are not automatically detected by the updated installer. Therefore, uninstall any previous version of BASEMENT e.g. using the link in the Start Menu before installing the newest version.
