Error in reading mass density

[jaesoo...@gmail.com]

Hello
I used pyNastran to read my bdf file.
Because my model uses mm/ton Unit.
It has material property as follows.

MID E G Nu Rho
MAT1 3 236000. 79230.8 .3 9.5-9

But pyNastran cannot read the mass density(Rho).
I think this is because of the its scale. It is 9.5-9 [Ton/mm^3]
Other material properties has bigger scale (10 to the -8 ) is read well.

I tried to fix this problem but i can't.
Please help me.
