symfem.moments._extract_moment_data(moment_data: MomentTypeInput, sub_type: str) → MomentType

Get the information for a moment.

Parameters:

  • moment_data – The moment data

  • sub_type – The subentity type

Returns:

The moment type, finite elment, order, mapping, and keyword arguments for the moment

symfem.moments.make_integral_moment_dofs(reference: symfem.references.Reference, vertices: MomentTypeInput | None = None, edges: MomentTypeInput | None = None, faces: MomentTypeInput | None = None, volumes: MomentTypeInput | None = None, cells: MomentTypeInput | None = None, facets: MomentTypeInput | None = None, ridges: MomentTypeInput | None = None, peaks: MomentTypeInput | None = None) → List[symfem.functionals.BaseFunctional]

Generate DOFs due to integral moments on sub entities.

Parameters:

  • reference – The reference cell.

  • vertices – DOFs on dimension 0 entities.

  • edges – DOFs on dimension 1 entities.

  • faces – DOFs on dimension 2 entities.

  • volumes – DOFs on dimension 3 entities.

  • cells – DOFs on codimension 0 entities.

  • facets – DOFs on codimension 1 entities.

  • ridges – DOFs on codimension 2 entities.

  • peaks – DOFs on codimension 3 entities.

Returns:

A list of DOFs for the element
