How To work on ODB file?

Hello,

I am looking for how to apply load on ODB File,

let me explain my problem, In my problem one part (Bush) should be fixed in step 1 and later after seal resting (compression of seal) bush should have one linear degree of freedom to free (it can translate max 0.007 mm).

My approach is step-1 fix the bush generate the results and later export the deformed seal and results in input of new file, and later change Bc's accordingly.

How to do import deformed results (ODB file) as fresh file.

or Any method is there to set bc as fix in step-1 and later change the bc to one translation free in step-2.

Thanks in advance,
