Mesh isn't imported from predefined field

Hello!

I have a file containing two models; the second model is a copy of the first, and it only serves to simulate springback. I used a predefined field to import the bending results from the first model. The thing is, the meshing in the second model is different from the first, and I can't redefine the meshing in that model because a warning appears, stating that the meshing controls can't be changed because they are imported from the predefined field...

Can someone help me on the subject? I thought the mesh was imported from one to another...
