OGSTools 0.8.1 Release Notes

Python 3.12-3.14
OGS 6.5.8

1/June/2026

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>/
