We strive to release major versions of our products at least once a year, and shonDy 2026.0.0 is this year’s major release. It introduces Python scripting and AI-assisted automation, geometry inspection and repair tools, an optional multigrid pressure solver, and LS-MPS with continuous particle refinement, alongside many new result quantities, post-processing filters, and fixes in both the user interface and the solver.
With this release, shonDy also gets a new version naming: the version number now starts with the year of release, which makes 2026.0.0 the direct successor to 2.7.8.
