Numeric precision lost upon entry into HyperMesh input box

I am using HyperMesh with the Optistruct user profile.

 

When entering values into the input fields they are converted to scientific notation and in the process lose significant figures.

 

The example attached is for a PBUSH stiffness.

Entered value 17500 (which is small enough to be written into the 8 character field of the bulk data file)

HyperMesh changes it to 1.8E+004, 18000

 

Writing the bulk data file using long format template makes no difference as the value is stored incorrectly inside HyperMesh

 

How can I change this crazy behaviour?

 

Thanks,

Brett

    hi, Brett

    1.8e+004 is just displayed value on card editor,

    exact value is always stored in hm with full precision

    and output value (to bulk file) is round off to 8 digits in style of real number

    so output value is still 17500, unless you changed format in pbush.tpl file
