v0.25.0

Release date: 2026-08-25

Early Access

The Luminary Cloud API and Python SDK are Early Access features that are still under development. View the Luminary Cloud Early Access Terms. The interface may change, and you may need to migrate or discard scripts and configuration files multiple times before v1.0.0 is released. In the future, migrations may also be necessary when upgrading to new major versions of the SDK (e.g. v2.0.0).

Release Notes

This release adds a tessellation edge-length cap for STL geometry export, lets line-sample data extracts sample evenly along the line, adds simulation template validation, and fixes SDK data extracts.

Breaking Changes

  • This release contains a breaking API change that affects only limited-release Physics AI functionality. If you use it, upgrade to this version; no other workflows are affected.

Features

  • New TessellationParams.max_edge_length_fraction on STL geometry export caps triangle edge length at a fraction of the body’s bounding-box diagonal. Unlike target_triangle_count, it is a direct single-pass cap with no iterative search, so it is also faster to export. Combine with max_aspect_ratio=1 for near-uniform triangles across flat regions.

  • vis.LineSample accepts n_samples, the number of evenly-spaced points to sample along the line, with fields interpolated at each point. Leaving it unset keeps the existing behavior of one sample wherever the line crosses a cell face. Values outside [2, 1000] raise a ValueError.

  • New Project.validate_simulation_template() runs the same checks as create_simulation() — mesh compatibility, named variable resolution, boundary condition matching — against a mesh without creating a simulation, and returns (is_valid, messages).

Deprecations

None.

Migration Guide

No migration is required unless you use the limited-release Physics AI functionality noted above; if you do, upgrade to this SDK version.
