Acoustic Structure Interaction Boundary Condition

I am attempting to model an ultrasonic wave propagating out of a solid into a fluid. I chose the normal acceleration BC in the acoustic domain at the boundary between the solid and the fluid. However, the model wants an expression for the nromal accelaration and I am not sure what to use for this expression. Can anyone help?

Setup for the fluid part:
Boundary conditions: normal acceleration
nx_acpn*u_tt_acpn+ny_acpn*v_tt_acpn
Setup for the fluid part: Boundary conditions: normal acceleration nx_acpn*u_tt_acpn+ny_acpn*v_tt_acpn
