Hi Nek's,<br>
<br>
I have a home-made global stability code, but in order to use it I
first need to compute the derivatives of my base flow: dUdX, dUdY,
dVdX, dVdY.<br>
How could one compute these derivatives using Nek 5k and drop them
along with X Y U V in the blah.f**** file (or perhaps another .f****
file) ? I assume I have to make use of the subroutine <b>dudxyz
(du,u,rm1,sm1,tm1,jm1,imsh,isd)</b>, but I'm not sure what to put as
inputs.<br>
<br>
Regards,<br>
JC<br>
