[Nek5000-users] stokes flow with time-dependent boundary

[nek5000-users at lists.mcs.anl.gov]

Hello, guys,

i am a new guy to Nek5000, i saw the manual of nek5000 that it can solve 
the steady stokes flow.
i guess when i solve such a flow, do i need to set it as a transient 
simulation with time-derivative term included to get  a steady-state 
solution? or, i can solve it by a direct solver method to get the 
solution immediately?

since i want to add some time-dependent boundary condition for the 
steady stokes flow, so it will be pretty nice if i can solve it using 
the direct solver, for each time step, i solve one stokes flow; if 
nek5000 cannot solve it in such a way, i guess i have to use the first 
way; then for each time step i have to solve a transient problem to 
approach the steady state with some artificial time step used.

i am not sure if i have stated my problem clearly. hopefully you guys 
have some experience on the feasibility of the two ways mentioned above. 
Thank you in advance.
