Due to your help, I can apply ZeroBoundaryCondition for pressure by adding
//test for strong boundary condtion
std::map boundary_values_strong;
doh. thanks!

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..?

Great, thanks! I have started Candi now - thanks to yourself and Uwe.

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

Phil -- I suspect it has to do with the errors during Trilinos configuration,
where it tries to find some load file but can't find it.
That said, do you
Hi Wolfgang,
Here is the full compilation, with the cmake. As I say, I can't see
immediately where the issue is.

I'm sorry, I should have include "part for boundary of pressure"
What I mean by "part for boundary pressure in assemble_system" is (in
step-20)
for (unsigned int face_no=0;
face_no::faces_per_cell;
++face_no)
if (cell->at_boundary(face_no))

Dear Phil,
to compile and use aspect, you need more dependencies (like Trilinos,
p4est, MPI) for the deal.II library.
To simplify your life, you can use the automated build script as announced
