I have a cross-section [y,z] complex velocity field in a section that is variable by function H[y]=z.
I would like to have a dynamic system (like Manipulate for example) to change z and have the plot of the velocity at fixed z.

This work in "static" way:

z = -5;
Plot[{Re[v[y, z]],
Im[v[y, z]]}, {y,
y /. Solve[H[y] == z, y, Reals][[1]][[1]],
y /. Solve[H[y] == z, y, Reals][[2]][[1]]},
PlotRange -> {{0, B}, {-0.1, 0.1}}]

How to make it dynamic? the following doesn't work:

Manipulate[Plot[{Re[v[y, z]],
Im[v[y, z]]}, {y,
y /. Solve[H[y] == z, y, Reals][[1]][[1]],
y /. Solve[H[y] == z, y, Reals][[2]][[1]]},
PlotRange -> {{0, B}, {-0.1, 0.1}}],{z,-10,0}]

Thanks
Jonny
