[Nek5000-users] Time-dependent Boundary Condition

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

Hi,

I want to simulate a 2D test case with time-dependent velocity  
boundary condition with the following form:
ux = A sin(2*pi*t)

I implemented the BC as velocity (v) in rea file and as
ux=A*sin(2*pi*time)
in userbc subroutine. Looking at the results, it seems that the BC is  
not enforced correctly and the velocity is zero at the boundary. I  
wonder if you could help me in this regard.

Regards,
Alireza
