[Nek5000-users] Stream function

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

Hi David,

There is a streamfunction option in postnek, but none
in nek proper.

The postnek one is very easy to use --

SET QUANTITY
STREAMFUNCTION

SET PLOT FORMAT
SCALAR
CONTOUR LINES

SET ATTRIBUTE
SET RESOLUTION
COLOR FILL
30
CONTOUR LINES
40 (say)

PLOT

Paul
