phase velocity and group velocity of Lamb Waves

Hi Everyone,
I made a cylindrical model surrounded by liquid model made of water, this model want simulate a part of carotid in the human neck.
I set the liquid and solid domains about all the geometry and had a Acustic-Solid Interections with transient study to calculate the displacement of a couple of points in the cylidric surface.
The Plane when i want show the displacement is parallel to the cylindric's axis and perpendicular to wave's plane.
Now i have to calculate the phase velocity and velocity of group of the wave used to sonificate my model, so can I use a Solid Mechanics node with other or same boundaries conditions to arrive at this graphs?
Or more in general can I see this kind of graphs with this node or have I to use other one?

Thanks for all

best regards
