Hello.

I have a 2-D model. In post-processing, I am able to visualize the surface plot of a variable A. I can also see the surface plot of another variable B in the same model. How can I visualize the surface plot of A/B ? Tried different basic attempts. Non of them is working.

What happens if you create a Surface plot, enter A/B as Expression, and click on Plot?

It shows zero amplitude all over the surface, which can't be true.

And non-of the B values are zero.

If you post the model here, or send it to COMSOL Support, then I think that it will be possible to explain the behavior that you observe.
