Add elements of type elementType classified on the entity of tag tag. elementTags contains the tags (unique, strictly positive identifiers) of the elements of the corresponding type. nodeTags is a vector of length equal to the number of elements times the number N of nodes per element, that contains the node tags of all the elements, concatenated: [e1n1, e1n2, ..., e1nN, e2n1, ...]. If the elementTag vector is empty, new tags are automatically assigned to the elements.
