This set of functions gives a pointer to dof descriptions and tests the compatibility between two dof descriptions.
A dof description describes a type of dof (Lagrange type, Hermite type ...) in order to be able to say wether two dofs are to be identified or not. The construction of dof type with the tensorial product is taken into account, making the dof_description structure a little bit complex (this structure will probably evoluate in the future).
| pdof_description getfem::lagrange_dof | ( | dim_type | d | ) |
Description of a unique dof of lagrange type (value at the node).
| d | the dimension of the reference element (2 for triangles, 3 for tetrahedrons ...) |

| pdof_description getfem::derivative_dof | ( | dim_type | d, |
| dim_type | r | ||
| ) |
Description of a unique dof of derivative type.
(a derivative at the node).
| d | the dimension of the reference element. |
| r | corresponds to the variable number for which the derivative is taken (0 <= r < d) |

| dim_type | num_der2 | ||
| ) |
Description of a unique dof of second derivative type.
