## Model.mesh\_query(name, position, selection='all', entity=None, entities=None, simulate=False, component=None)

Query arbitrary data from the mesh of the model.

### Parameters

- name: Data type to query: 
    - labels, indices
    - etypes
    - coordinates
    - angles (needs component)
    - thickness (needs component)
    - normals
    - orientations, ref\_directions, fiber\_directions, transverse\_directions
    - draped\_fiber\_directions, draped\_transverse\_directions
    - ply\_offsets (offset vector)
    - area, volume, mass, price
    - cog (centre of gravity)
    - offset (offset in the thickness direction)
- component: Defines the component. Needed for name=’angles’ or ‘thickness’. 
    - angles: Valid options: design\_angle (default), shear, draped\_fiber\_angle, and draped\_transverse\_angle.
    - thickness: Valid options: thickness (default), and relative\_thickness\_correction.
- position: Position where data is queried: 
    - nodal
    - centroid
    - element\_nodal
- selection: The selection set determines the selected nodes and elements. Can be given as string (‘sel0’-‘sel5’ or ‘all’) or ObjectSelection object such as 
    - model.selection
    - scene.active\_set
- entity: Specialized queries require the specification of an additional associated entity. For instance, an oriented element set is needed to compute orientations. Entity can be given as NamedGraphObjects or vertex descriptor.
- entities: If a list of entities is given, then the query will also compute and return a list of results, with one array for each entity.
- simulate: Whether the query is only simulated to test if it will return data. If this flag is set the mesh\_query(…) function will only return 0 or 1.
