## Version 5.2.0 - Simulation, Engineering Workflows & Collaboration

Version 5.2 expands Davinci's engineering analysis capabilities while making CAD workflows, project collaboration, and automation more reliable.

### Simulation & Engineering Analysis

* Expanded simulation support across structural, dynamic, transient, thermal, fluid, fatigue, contact, acoustics, radiation, and environmental analysis
* Added improved mesh quality and accuracy with second-order tetrahedral elements, adaptive meshing, and mesh-convergence reporting
* Added expanded optics and STOP analysis, including telescope models, ray tracing, coronagraphs, deformable mirrors, stray light, wavefronts, PSF, and MTF results
* Added clearer simulation setup, compilation, verification, and result reporting
* Added interactive explorer panels for inspecting simulation results and comparing outputs across design studies

### CAD, Assemblies & Motion

* Improved assembly solving, mates, imported-part interfaces, collision checks, and assembly diagnostics
* STEP imports now preserve detected geometric features to support more reliable assembly workflows
* Added motion-study stages, tracked mechanisms, closed-path motion, pose playback, and stored motion artifacts
* Improved joint control, motion-study validation, compile error reporting, and CAD authoring feedback

### Agent & Automation

* Code objects can now access compiled studies through the simulation API to describe, query, and sample results
* Added a Python simulation interface for runtime analysis workflows
* Improved agent support for simulation authoring, imported geometry, project context, and persistent artifacts
* Added clearer validation messages, simulation staleness information, and recovery guidance

### Teams, Task Cards & Project Management

* Added required fields and configurable mover-assignment actions for task-card status transitions
* Improved kanban filters, sprint handling, close-on-move behavior, card refreshes, and team board layouts
* Added project memory capabilities and more reliable project storage accounting
* Updated the public API and Python and TypeScript SDKs for the latest team and task-card workflows

### Workspace & Documents

* Improved simulation, assembly, and motion-study views in the workspace
* Improved document tables, slides, PDF forms, signatures, exports, and collaborative editing
* Added a faster search path for large projects to reduce client-side lag
* Added numerous reliability fixes across workspace panels, previews, and rendered results
