[Nek5000-users] Further to ffx, ffy and ffz

Dear Paul and Phillip,

Thanks for your reply.

Paul, I am sorry say that I made an mistake for my question last time.

I intended to ask if I set
P54=-1
P55=1
ffx: non-zero (x is streamwise)

Will the fluid be changed by the effect of non-zero ffx which I am thinking
can be considered as the effect of the particles acting on the fluid while
I am doing the lagrangian paticle tracking.

By the way, can I fix the pressure gradient as (Re_t/Re_b)^2 for the pipe
as well?

Kind regards,

Zhai
