------- Comment #20 from dominiq at lps dot ens dot fr 2010-04-14 13:06 -------
I have been able to get the following values before the crash:

ie = I - 1
debe = DEBav(ie)
debs = DEBav(I)
deve = XA(ie)*debe + XB(ie)
devs = XA(I)*debs + XB(I)
sec = SCApa(I)
debm = (deve+devs)/2.D+00
eps = 1.D+00
IF ( debm.LT.0. ) eps = -1.D+00
vis = (r+s*tf)/3600.D+00
Re = eps*debm*DIAhy/(vis*sec)
So if I= 13, 14, or 15, Re is a NaN.
