Hi,

when adding new material into the Material Library, and setting everything but the density to NA (i.e. only the density is set to some value, other values are not set), then:

- after Apply, SWX suggests that because the Poisson's Ration is not defined, it will use the default value of 0.0 [OK]

- the Program does not set anything, the Poisson's Ration remains empty

And the issue occures, when editing the material again later. IMO, SWX shoudl set the Pooisson;s Ration to 0.0, if it is required. If not, then should not complain about it. There is no other choice.

SWX: 2013 B3

OS: Win7 64bit

Cheers,

M
