[CIG-SHORT] Dirichlet displacement-normal boundary condition?

[Brad Aagaard]

Scott,

Specifying a Dirichlet boundary condition using an orientation other 
than the coordinate axes is not implemented. I think you are the first 
person to request this feature. We do have a DirichletBoundary setup 
that associates a boundary mesh with a Dirichlet boundary condition so 
the orientation information could be setup. We will add this to a list 
of features to consider adding in a future release (right now we have 
several features to add that are higher priority).

Regards,
Brad
