Right... "Duplicata" creates a duplicate "display" of the view, but the
core data is not duplicated (so that you only use the memory once). 
Since Plugin(DiplacementRaise) actually modifies the data inside the 
view, you need to load the view several times in memory. Here is a 
modified script that should do what you want:

Merge "U.pos";
For i In {0:View[0].NbTimeStep-1}
   Merge "Gap.pos";
   View[i+1].TimeStep = i; // choose what to display
   Plugin(DisplacementRaise).iView=i+1;
   Plugin(DisplacementRaise).dView=0;
   Plugin(DisplacementRaise).dTimeStep=i;
   Plugin(DisplacementRaise).Factor=0.1;
   Plugin(DisplacementRaise).Run;
EndFor
Delete View[0];

Best,

Christophe

PS: we should probably think about a simpler way to do this...
