How to set displacement from study 1 as prescribed displacement in study 2?

Hey,

I have a trouble with defining a prescribed displacement.

Let's say that i received displacement of the edge caused by heating of sample. But displacement of this edge is different in every point of its length.

I want to keep this displacement as prescibed displacement condition in next study. So i can't just add condition prescibed diplacement in y=a, becouse it's more like ax*bx^2.

I tried to use mod1.u as prescribed in y, but it's not working or I doing something wrong.

How can I solve this problem?

Kind Regards

Robert
