Hi, i have a simple question, im work in Solid Mechanics.
My model consists of a cube, apply a force per unit area on one side (face load). Using frequencies of 100 to 2000 [Hz]. According to the theory, each point will have an equation of motion X (x, y, z, t) = Xo (x, y, z) sin (wt + phase).
When I get the results, the graph of COMSOL is Xo (x, y, z)? O is a snapshot at any time to? To that value?
Sorry, my level of english is low.

Hi
first in structural learn to understand the sublimities of (x,y,z) (X,Y,Z) and (u,v,w) (check the doc carefully)
Then you must tell us which solver: time series full inertia terms or quasi static or frequency response with a harmonic development ?
and if its u,v,w you are looking at it at a given time t if you are in time stepping (you define that in the plot node) or at a frequency f (then its the amplitude).
note that you do not get complex displacements if you do not add some damping (sub node to linear material)

Good luck
