Plotting ratio of displacement

Hi,
I am using COMSOL 4.2.1.166, and am simulating a circular membrane as a Structural mechanics 'plate'. I simulate to get the mode shape of the fundamental mode for a uniform load in the normal direction and intial stress in the x-direction. I now would like to plot the ratio of the vertical defelction along the x and y axis as a function of the radius, i.e. something like
w(x=0,y,z=0)/w(x,y=0,z=0)
with vertical displacement w of the fundamental mode vibration. I can't find how to access the vertical displacement along a line (e.g. x-axis w(x,y=0,z=0) ) to be able to plot it. Does anyone know how this can be done?

Hi,
You can add a General Extrusion coupling operator which maps X to Y and Y to X. Then you can do a line plot along the x-axis of e.g. 'genext1(w)/w'.
