[Nek5000-users] Instantaneous velocity field

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

Hello,

Thank you for the reply. I meant the instantaneous velocity field for the domain (u(x,y,z),v(x,y,z),w(x,y,z)) at some certain time step (istep).

Regards,

Tim

do you mean how to write out an instantaneous field, or to generate an

initial condition?
