Maybe it simply doesn't need more memory. Sometimes more cores used in solution don't speed it up. From my experience, when Ansys is trying to use more memory than available it will use your hard disc ...

It could be a matter of different results coordinate systems (RSYS, Options for Output) or a scale.

How did you import your results into Workbench? Could you write it step by step?
