Hello everybody,
I'm trying to understand how PAM STAMP generates the FLD with "autoKeeler" option.

The FLD0 is clear. FLC0 = ln[1 + (23.3 + 14.13t)n/21].
The left side is also clear, by Goodwin method. e1 = FLC0 - e2, where e2 <= 0
But for the right side... I'm not sure. The Pam Stamp documentation says that uses Goodwin's and Keeler's law, but searching in google, the empirical equation that I find for Keeler doesn't match with PAM STAMP.
Anybody knows which formula is used by Pam Stamp?

I just attached a comparative with the parameters: n = 0.2, t = 1.5 mm

Thanks in advances
