[Paraview] Is it possible to scale a velocity field in paraview by a scalar and to sum the two velocity field too?

[Eleonora Piersanti]

I have two velocity field coming from an eigenproblem. One corresponds to the real part of the eigenvector and one to the imaginary part.Since I would normalize the phase I need to scale them and to sum them in some way. Is it possible to do it directly with paraview?
Kind regards,Eleonora
