[Nek5000-users] istep

Thanks again,

I just thought there was an easier way and it seemed strange to me that I
couldn't get the cumulative timestep. I don't usually change dt so for now I
just use int(time/dt). And I don't really use fld files ;-), since we
already have a fantastic inhouse visualization software (
http://persons.unik.no/andershe/papers/voluviz/voluviz.html).
