how to couple two different physics

Please login with a confirmed email address before reporting spam

Hello.

I'm trying to simulate and get result about how EHD Inks are changed by electric currents. I already downloaded example(inkjet.mph) from this repository(https://www.comsol.com/model/inkjet-nozzle-8212-level-set-method-1445) Using this example, I added electric currents and did compute how inks were getting changed under each voltage while inks were flowing. but the thing is the results were out seperately such as one of fluid model and one of electric currents model. So I tried to couple "Levelset, flow fluid" and "electric currents". but whenever I checked Levelset or flow fluid with electric currents, it doesn't show available physic in "mutiphysics coupling" button in physic tab. how can I simulate what I want?

plz help me out.

thx in advance.
