[Nek5000-users] Unable to read the coefficient of lift and drag

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

Dear Sir

I am trying to run a simulation involving a plunging airfoil. For this
purpose I have created two geometry files, one consisting of the airfoil &
the other consisting of the outer mesh. My aim is to find the coefficient
of lift ( Cl )and drag ( Cd ) & for this purpose i introduced a code in the
subroutine function usrchk(). Upon compilation, I get the following error:

In function `userchk_':
naca0012.f:(.text+0x42b): undefined reference to `set_ob_'
collect2: ld returned 1 exit status
make: *** [nek5000] Error 1


I am attaching herewith the files for your perusal.

Looking forward to your positive reply.
