Dear Jean-Paul
Sorry for my belated reply.
I was solving other problems...
Anyway, thank you for your reply.
I will study what you mention.
thank you
Kyusik.

Thanks for your reply again.

Due to your help, I can apply ZeroBoundaryCondition for pressure by adding
//test for strong boundary condtion
std::map boundary_values_strong;
You mention that
The difference that in step-3, you are imposing *strong* boundary
conditions,
whereas in step-20, you are imposing *weak* boundary conditions.
Then, is there anyway to use strong boundary condition using FESystem
Yes, of course. Via VectorTools::interpolate_bounda
Thank you very much your kind reply.
Could I have one more question..?

Kysusik,
I'm studying step-20 tutorial example. But, I can't understand it, because it
seems to have different things compared to step-3 in terms of boundary
condition.
In the introduction of step-3, it is said that
∫Ω∇φ⋅∇u−∫∂Ωφn⋅∇u=∫Ωφf.
The test function φ has to satisfy the same kind of
