Use this ONLY for long-running background computations that do NOT touch the
FreeCAD GUI or mutate the FreeCAD document tree directly.

This tool runs the submitted code in a background thread and returns
immediately. Because it does not run on FreeCAD's main GUI thread, the code
must NOT call FreeCADGui APIs, manipulate the active view or selection, create
or edit document objects, change object properties, call doc.recompute(), or
save documents.

For code that touches FreeCAD documents, document objects, FreeCADGui, the
active view, selection, recompute, or save operations, use execute_code instead.
execute_code runs on the FreeCAD GUI thread and is the safe default for normal
FreeCAD automation.

Use execute_code_async only for background-safe work such as long-running
pure OCCT geometry calculations (e.g. fuse/cut/loft on already-fetched shapes)
or other CPU-bound computations that do not interact with the document or GUI.

Typical usage pattern:
1. Fetch shapes into local variables first (via execute_code on the GUI thread).
2. Store intermediate results in a module-level Python variable (not in the
   FreeCAD document) so execute_code can read them later.
3. Run the heavy computation via execute_code_async.
4. After the expected computation time has elapsed, apply results to the
   document via execute_code (which runs on the GUI thread).

Args:
    code: Background-safe Python code to execute.

Returns:
    A message confirming that background execution has started.

Args:
    doc_name: The name of the document to get the object from.
    obj_name: The name of the object to get.
    include_screenshot: Whether to return a screenshot of the document (default True).
        Set to False to save tokens when only the object data is needed.
    view_name: The view orientation of the returned screenshot (default "Isometric").

Returns:
    The object and a screenshot of the object.

Args:
    doc_name: The name of the document to get the objects from.
    include_screenshot: Whether to return a screenshot of the document (default True).
        Set to False to save tokens when only the object data is needed.
    view_name: The view orientation of the returned screenshot (default "Isometric").

Returns:
    A list of objects in the document and a screenshot of the document.

Args:
    view_name: The name of the view to get the screenshot of.
    The following views are available:
    - "Isometric"
    - "Front"
    - "Top"
    - "Right"
    - "Back"
    - "Left"
    - "Bottom"
    - "Dimetric"
    - "Trimetric"
    width: The width of the screenshot in pixels. If not specified, uses the viewport width.
    height: The height of the screenshot in pixels. If not specified, uses the viewport height.
    focus_object: The name of the object to focus on. If not specified, fits all objects in the view.

Returns:
    A screenshot of the active view.

Args:
    relative_path: The relative path of the part to insert.
    include_screenshot: Whether to return a screenshot of the model (default True).
        Set to False to save tokens when visual feedback is not needed,
        e.g. for intermediate steps in a longer sequence of changes.
    view_name: The view orientation of the returned screenshot (default "Isometric").
        Pick the view that best shows the change being made.

Returns:
    A message indicating the success or failure of the part insertion and a screenshot of the object.

Returns:
    A list of document names.

Use this AFTER the document's .FCStd file has been modified by
something outside of FreeCAD's GUI process — for example, a
headless `freecadcmd` script that edited and saved the file. The
open GUI document is otherwise unaware of on-disk changes; this
tool closes the stale in-memory copy and reopens the file from
disk so the GUI shows current geometry.

Args:
    doc_name: The name of the open document to reload. Must match
        the name shown by ``list_documents``.

Returns:
    A message confirming the document was reloaded, or describing
    the failure (document not loaded, no associated file, etc).

Examples:
    ```json
    {
        "doc_name": "chassis"
    }
    ```

Prerequisites in the document:
- A Part-derived solid (e.g. Part::Box, PartDesign::Body) acting as the geometry.
- A Fem::AnalysisPython container created via `create_object`.
- A Fem::MaterialCommon assigned to the geometry, added to the analysis.
- A Fem::FemMeshGmsh referencing the geometry, added to the analysis (the
  mesh is generated automatically when created via `create_object`).
- At least one Fem::ConstraintFixed and one Fem::ConstraintForce (or
  ConstraintPressure) bound to faces of the geometry, added to the analysis.

A SolverCcxTools is auto-created if the analysis has none.

The solver runs synchronously on the FreeCAD GUI thread and blocks all
other RPC calls for its duration; do not fan out parallel requests.

Returns max von Mises stress (MPa), max/min displacement (mm), node count,
and the working directory CalculiX wrote to. On failure, returns the
prerequisite-check or solver error along with the working directory for
triage.

Args:
    doc_name: Name of the FreeCAD document.
    analysis_name: Name of the Fem::AnalysisPython object.
    timeout: Seconds to wait for the solver (default 600).
    include_screenshot: Whether to return a screenshot of the model (default True).
        Set to False to save tokens when only the numeric results are needed.
    view_name: The view orientation of the returned screenshot (default "Isometric").
