9 years ago Boundary_lock has no call to scattering. This is your most likely point of failure.

}However, when it gets used in envelope_generator::scattering(), the model that actually gets called is scattering_constant(-300.0) which also happens to be the default for the _scattering member of boundary_model.
void envelope_generator::scattering( size_t interface, const wposition1& location,
const seq_vector& frequencies, double de_incident,
double de_scattered, double az_incident, double az_scattered,

We know that it is is scattering_constant that is getting called:
1) Because we used the debugger to step into the method. 2) The scattering strength is always returned as 1e-30, which is -300 dB in linear units.
