I am trying to couple electrostatic with fsi physics to simulate a piezoelectric cantilever actuator beam moving inside a fluid. I use force calculation in es and then body load on fsi and solid. When I try to solve it this error appears.

Undefined variable.
- Variable: comp1.es.unTy
- Geometry: geom1
- Boundary: 5

Which I don't understand, because the stress tensor is suposed to be caulculated using force calculation. Can anybody help me please?
