[Nek5000-users] SETDTC message

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

Hi Frank,

Set DT < 0 (param 12 in .rea file) and then dt = |param(12)| for
the duration of the run.  (Sometimes you still get the message though...)

I am coming across the following message "Problem calculating new DT
Discriminant" in subroutine "SETDTC" where a new timestep based on the
CFL condition is computed.  Aside from what the message means, how can
one turn off variable time stepping (which I assume is occurring since
this subroutine is being called).

Cheers,
Frank
