A problem with two physics.

Hello everyone,

I am trying to simulate a simple problem which includes a fluid channel and a piezoelectric splitter. I used two physics: "piezoelectric devices" and "laminar flow", each of them works fine by itself. I would like to see how the flow looks like when the splitter is deformed by applying a voltage, when I tried to plot the flow pressure distribution with deformation applied, it gave me an error as attached. The simulation file is also attached. (4.3a)

Anyone could help? Thanks!
