Importing strain values in XFEM

Hi,

Does anyone know how to import the strain values from simulation run in one model, into an XFEM model? I am trying to model creep seprately in one model, and wanted to import the strain values of each step in that model (10 steps, representing 100 yars), into an XFEM model to find out when the crack initiates and propagates in duration of 100 years.

Thank you very much,

Sam
