Adjusting boundary load based on deformation

Hello,
I am designing an object, on which a boundary load acts. When the object deforms, the direction of the load must change based on the deformed coordinates of a point of the object. What I tried, was add a variable, selected the desired point, added root.y and root.z, and gave them a name, Rooty and Rootz. I added a boundary load in the multibody dynamics part. I added a force in the Z-direction like this: cos(atan(Rootz/Rooty)). The load is added in increments. When I compute this, I get an error stating that there is an undefined variable: comp1.Rootz. Does somebody know how I can adjust the boundary load, based on the deformed coordinates?
