I am modelling the formation of standing acoustic waves inside of a cavity network. My model agrees with experimental results on a qualitative level.

Now I am trying to find ways to minimize formation of standing waves. For this I need a way to quantify my results. My first thought is that by taking the average and standard deviation of the pressure inside my cavity, I'll be able to tell how "strong" the standing wave effect is. A larger standard deviation would suggest to me that the standing waves aren't dampened as much or are driven stronger than a result with a smaller standard deviation. A standard deviation of 0 would tell me that there is no wave formation at all and this is basically the trivial answer where nothing is happening in the system.

Okay, so now to the COMSOL part: I have no idea how I would go about doing this, if it's at all possible. I have tried using volume averages and the like, but those only seem to work when I select multiple data sets from the same study. It will take an average of those multiple data sets instead.

Is COMSOL even capable of doing what I want? If not, does anybody have any suggestions on where to proceed from here? Thank you.
