Is it possible to impose a linear constraint on the variables in a system using a DirichletBoundary object?
The case I'm thinking of is in elasticity, where you want set the displacement in the normal (or tangential) direction on a surface. In that case we want "n \dot (u,v,w) = normal_displacement" on the boundary. I've only used DirichletBoundary to impose independent conditions on each variable, so I assume that a condition like "n \dot (u,v,w) = normal_displacement" isn't possible yet? If that's the case, I'd be happy to work on it. Roy: Do you have any comments on where to start, and how much work it would require?
