The boundary density is calculated by the inverse_state_equation with extrapolated fluid pressure. Wouldn't it have a similar effect if you pass a background_pressure to the state_equation for the boundary model?

That is, the pressure is extrapolated from the fluid, but the density is tuned by the artificial state_equation with background_pressure.

Have you tried this? Or did I miss something?
