mesh_query

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.
