Is there a list of variables that are associated with a module? I want to find the notation for the Maxwell Stress Tensor in the Electrostatics module, but I have no idea where to look. I tried the manual and other help fields, but I couldn't find anything.

Often times I see various variables referenced in tutorial models and they just use the names as if it were totally obvious what they are called.

You can find the mathematical definitions of variables derived from the primary variables by turning on "Equation View" (by using the "Show" button - the one with the eye icon at the top of the Model Builder) and then browsing through the model tree. Many of those expressions rely on the syntax and operators detailed in the Reference Manual, version 5.2, Chapter 5.

Note also that the COMSOL names of many quantities of interest can be figured from the post-processing tools: e.g. select "Electric potential" as the quantity to postprocess and COMSOL will show that the expression for it is, say, V.
Best regards,

Yes! Thank you so much!

I had been using the post-processing variables for what I can, but obviously not everything is included there.
