Dirichlet BC on an arbitrary point

[gongzhulingshi]

How to impose Dirichlet boundary conditions on arbitrary points rather than the entire boundary? I want to apply a concentrated load on a boundary in the form of displacement, but the BCs can only be imposed when the load function is defined for the entire boundary.

Hi @gongzhulingshi , I think that it is complicated for an arbitrary point - we'll have to look into that. For a corner, however, we have gsBoundaryConditions::addCornerValue. This might help you already.
