Re: [ATM] Supporting those pesky ultrathin mirrors
David,

I am not FEA expert but as far as I know PLOP is a FEA based
analysis program. I suspect that it is possible to calculate
support points and then discard some of them without negating
premises or preconditions used by PLOP to calculate remained points.
If that is true than it is irrelevant if remaining points are PLOP
calculated or guessed by intuition based "black magic".
Using PLOP in this way reminds me on "Cargo Cult".

Can we please see the image of this design?
(If not available, Dale please send one after receiving the cell.
Thanks in advance.)
And what is the "marshmallow" in this context?
