[Nek5000-users] unusual quantities

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

Hi Mike,

I've taken a pass at setting something up to compute these.
See attached.

Other than testing that it compiles and runs, I've not tested
to see if it actually computing what you want.  If it's not,
I would guess that it's close...

Please have a look at the attached files.

In principle, you can use a script like the following

genbox << EOF
rb3d.box
EOF
genmap << EOF
rb3d
0.1
EOF
makenek rb3d

and be set to go with

nek rb3d

or

nekmpi rb3d 8

say.

You would adjust resolution by editing rb3d.box --- making
certain that the SIZE file is compliant.  In particular,
to get the z-integrals that you want you need to be certain that
lelx and lely are big enough so that they match the number of
elements in your x-y plane.   Ditto with nelx and nely, which
are set in the .usr file.  (The limits, lelx and lely, are set
in the SIZE file.)
