Hi NEKs,
for the validation of my simulation I need the 1st derivative of the
pressure and the 2nd of the velocity. When I use twice "call gradm1" to
calculate and "call outpost" to write the 2nd derivative for my velocity
field it works pretty well. But for the pressure field it goes wrong. I
think this is due to the fact, that the pressure meshed differently compared
to the velocity field. Does there exist a subroutine to calculate the
derivatives of the pressure or do I have to write something by my own??
Thanks a lot.
Best, Fred
