Get the nodes on the faces of type faceType (3 for triangular faces, 4 for quadrangular faces) of all elements of type elementType classified on the entity of tag tag. nodeTags contains the node tags of the faces for all elements: [e1f1n1, ..., e1f1nFaceType, e1f2n1, ...]. Data is returned by element, with elements in the same order as in getElements and getElementsByType. If primary is set, only the primary (corner) nodes of the faces are returned. If tag < 0, get the face nodes for all entities. If numTasks > 1, only compute and return the part of the data indexed by task.
