[Nek5000-users] Time-dependent Boundary Condition

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

Hi Alireza,

I would normally put something like:


       write(6,*) a,pi,time,ux
       stop


after the assign statement, run it, and see what happens.

Please let me know if that clarifies at all.

Also, how did you implement the bc?  Was it in genbox?

Did you specify:  'v  '   (v, followed by two spaces) ?

Best regards,

Paul
