Abaqus - How to import results from infinite element model to apply seismic analysis in same model with infinite elements.

 Hello, I am trying to perform static and seismic analysis for retaining wall model consisting of backfill and foundation soil. Actually I  have done static analysis on retaining wall by giving wall displacement of 40mm with gravity loading, considering infinite element in backfill and foundation soil and obtained the stresses. I want to now do seismic analysis on the same model but copying in new model so that I only need to add seismic step. I tried to solve it by copying deformed parts from the previous model and then apply eartqhyake motion in it by using predefined field option to call for stresses obtained in the previous job. But  Abaqus is showing error  writing it can't import infinite elements. Can u suggest me other alternative to do so as I need to perform both static and seismic analysis as part of my dissertation work?? I am attaching the image of my model for your reference.
