Add capability to compute nodal normals #1871

Closed andrsd closed 10 years ago

andrsd commented 10 years ago

When enforcing BCs strongly, we need the normal (sometimes). SInce the normal at a node is not defined uniquely, we need a formula to compute it. One way can be found in this paper: M. S. ENGELMAN AND R. L. SANI, THE IMPLEMENTATION OF NORMAL AND/OR TANGENTIAL BOUNDARY CONDITIONS IN FINITE ELEMENT CODES FOR INCOMPRESSIBLE FLUID FLOW, 1982.

Fixing nodal normals in parallel (refs #1871)

- the system had to be re-worked, now the normals are stored in aux variables instead of a system vector.
- also found a few bugs which has been fixed
