[firedrake] Applying bcs when using LinearSolver

Hi all, Say I have this: a = dot(grad(u),grad(v))*dx L = f*v*dx bcs = DirichletBC(...) A = assemble(a) b = assemble(L) solver = LinearSolver(A, ...) solver.solve(x,b) If I want to apply the DirichletBC's, I would use "A = assemble(a,bcs=bcs)." Is it necessary to also do this for b? Would it have any affect? Thanks, Justin
