How to visualise the 'output' of a Neumann boundary condition?

Hi,

I'm modelling calcium flux using the PDE Toolbox and I use a non-constant Neumann BC at one of the Faces of my model (its 3D).

I'd like to know what the actual value of the flux is throughout the duration of the modelling.

I can technically find the value of the flux if I un-silence (remove the ';' ) the Neumann BC, but that just prints the values at each time point.

Is there a way to save the value at each time-point into an array to be able to plot it and calculate the mean?

Thanks for the help!

I think the example

"Heat Transfer Problem on a Square"

under

will be helpful in your case.
