I need to use the expression V(z)-V(z-1). How can I address the value of V at point (z-1)?

Thanks.

The problem was because of v.4.0a. It works correctly in 4.1.

To address the variable V at (z-1), I defined the mapped coordinate system sys2 with sys2.z = z-1 and the general extrusion operator genext1 with sys2 as a destination map. genext1(V) gives the value of V(z-1).
