Thank you David.

exactly!

Yes, I have German Local.
After loading from the pull down menue the material properties, when I
replace the " , " by a " . " everything is fine. With
Zerodur I get now approx. 20% lower deformations than with Pyrex, which is
very reasonable.

p.s.
Kurt Schreckling, a German ATM fellow measured the flexing on an exacly
spherical 16" Sital mirror with Foucault. The mirror was put on a ring
support of 6.3" diameter and looked vertical. The tester was located
one floor above the mirror at the stairways (he did it at night, so no
family member could call him crazy) . See the setup at
http://www.astrotreff.de/topic.asp?TOPIC_ID=2476. The text is German but I
thick the method is clear.

I calculated with PLOP assuming a 6 point cell where the points are at the
same 6.3" diameter and got the same result - wow!

I see two interpretations:
1: The program and his measurements have exacly the same mistake 2: He
measured right and the program is great tool
