How to inverse compute_vertex_value

1

Hi all,
I am a new user of this software.

I am calculating displacement value by using compute_vertex_value. Is there any process to inverse the process?

For example,
displacement, u_value = u.compute_vertex_value

I want to know if there is any function that can do
u = u_value.value_to_vertex ??
