1/June/2026

Python 3.12-3.14 OGS 6.5.8

Changes (non API-breaking)

Bugfixes

• MeshSeries: could not be read if xdmf-file was a symbolic link
• added missing tools to cli interface (mergeMeshToBulkMesh, CreateAnchors)
• identifysubdomains will ignore anchor meshes to not wrongly overwrite the special id mapping
• fixed sorting of ot.plot.line in some edge cases
• A Matrix Variable transformed to the polar coordinate system (ot.variables.Matrix.to_polar()) is now also able to use .transform on a MeshSeries
• .xdmf MeshSeries which only contain points (and no cells) can now be properly read
• Project: Curves (bin) and chemical solver database (dat) are now copied and saved with Project
• Materiallib: fix bug with selecting multiple materials in a copy
• ip_mesh: fix for meshes with mixed cell types
• plot.contourf: fix when used in notebooks
• MeshSeries.from_data: fix save and scale behavior
• OGS-Restart: minor fixes

Features

• added the Class ogstools.mesh.IPdata to interface with the integration point metadata
• variable components can now be plotted via strings e.g. "displacement_x" will plot the same thing as ot.variables.displacement["x"]
• added standalone type hinted methods, to set parameters to a project per parameter type e.g. prj.parameters.set_constant_parameter / prj.parameters[name] = int_or_float or prj.parameters.set_function_parameter / prj.parameters[name] = str
• added prj.parameters.set_group_parameter
• ogsmonitor is now a standalone CLI tool (previously only usable from Jupyter notebooks). New CLI features include automatic port selection, pipe support, better error codes, and the logfile path is now a positional argument.
• temporary files are now all consistently written und /tmp/ogstools_<username>/<functionname>/
