[Nek5000-users] Problem with drag coefficient of ext_cyl

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

Hello,
 I just started my PhD work in FSI of NACA profile so I am using NEK5000
for the simulations. So, in order to start with NEK5000, first I try to
validate a very simple test case which is the flow around a 2D cylinder.
This test case is already in the example folder of the solver kit. So, I
try to simply run the test case and tried to compare the drag coefficient
with the given Re number. It was giving a wrong value. for example it gives
21 instead of 3.5 for Re 100.  I had changed the domain a bit according the
research papper I have. I used torque calc function to compute the drag.

Could you please help me to validate this test case? So that I can continue
with lmy moving cylinder test case and I will be more confident in NEK5000

Thanks

SIjo George
