Hi Ding, Sorry, a bit confused by the question. Do you mean in the velocity correction scheme? If so, we use a so-called high-order pressure boundary condition for the Poisson solve (this is documented in the book by Karniadakis and Sherwin and is in a paper somewhere), and the velocity conditions are imposed at the last Helmholtz solve step. Cheers, Dave

Dear Nektar group: Could you please give me some suggestions about the boundary condition for the first and second intermediate velocity field? Does it use the same with the real velocity boundary conditions.

Regards Your Sincerely Ding
