FEI Version of the Day
|Dof (LocalOrdinal rank, GlobalOrdinal id, LocalOrdinal field)|
Dof - mesh-degree-of-freedom.
A mesh-dof is the triple (rank, id, field).
Thus if the user chooses to give nodes a rank of 0 and the temperature field a label of 4, then the temperature at node 97 can be represented as the dof (0, 97, 4).
1. The Dof class is templated on the two integer types LocalOrdinal and GlobalOrdinal. Ranks and Fields have type LocalOrdinal, while ids have type GlobalOrdinal. The distinction is somewhat arbitrary, but the assumption is that there may be billions (or more?) ids, but probably far fewer distinct ranks or fields. So in extreme cases a user may wish to use a different type (larger) for ids than for the rank or field.
