OptiStruct Linear Static Analysis output significant digits

[timpap]

Hello to all,

I have asked exactly the same question in the Nastran forum. How to output more significant digits. The answer there was to output the *.op4 file. It worked perfectly.
I am trying to do the same with OS right now but it is not working.
Anybody of you knows how to output displacements with more significant digits than the default 5 ?

Thanks in advance
