Hi,

I don't know is it proper question or not

Q1) What are dependent variables and what is its significance in comsol and

Q2) Can we link two physics using them

Hossein Daneshpajooh

1) dependent variables are parameters which your model solved for them.

2) yes, You could couple two physics by contributing them in other physic equations.
