[Nek5000-users] Newby's question: Inflow IC / BC from external file

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

Hi Francesco,

Normally you would set the fluid BC in the .rea file to be "v  "  (v + 2 spaces)  ... then, in userbc() in the
.usr file you would do something like:

      ux=(1-y*y)

....

Does this approach work for you?

Paul

Subject: [Nek5000-users] Newby's question: Inflow IC / BC from external file

Hi Neks,

I'm new to this amazing software, and I'd like to better understand it in order to run some cases.

Right now I'm trying to impose a steady inflow velocity profile computed outside Nek as boundary / initial condition. I've found lots of threads about this, spread all over the forum, but i can't actually get how to "practically" do this.

I know this is a dull question, but i can't really sort it out; any help is greatly appreciated!
Thank you

Francesco
