[Nek5000-users] failed to write derivatives in one file

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

Thank you Paul,

I tried this way. It works.  the 9 derivatives have been written in 3 independent files. I  checked the data format, e.g. "vxd*****", it looks like

x y z dux duy duz

is it possible to put vyd and vzd together with vxd? like

x y z dux duy duz dvx dvy dyz dwx dwy dwz

then it will be much convenient to visualize the du in visit.
Thank you very much again!

Wei
