Re: Change interface for boundary conditions: operator() --> eval(). [...]
Would it be possible to design BoundaryConditions in an analogous way to
Function so that it knows something about "sub boundary
conditions" (like subfunctions)? A BoundaryCondtion would contain "sub
boundary conditions" for different terms in the pde. Rather then
pressure in 3D NSE being component i = 3 when applying BC's, it could be
set by another function.
