Stop condition in Electromechanics(emi)

I would like to implement a stop condition similar to what is described for a moving mesh problem.

The parametric study would stop when the mesh quality is lower than a certain value, inorder to prevent an inverted mesh.

For a moving mesh problem you add a stop condition with the following term:
mod1.ale.relVolMin-0.01

But what term should I use for an electromechanics simulation?
