Hi everyone,

I have a question about the loudspeaker tutorial in the `bempp-acoustic-tutorials`

by mscroggs.

In the code, `U_cone`

is defined as follows:

U_cone = 0.001 # Amplitude of the time-harmonic velocity of the cone in m/s

However, it doesn’t seem to be used anywhere in the code. Should `U_cone`

be multiplied by `n[2]`

in the following line?

@bempp.api.complex_callable

def u_total_callable(x, n, domain_index, result):

if domain_index == 2:

result[0] = n[2] # Should this be result[0] = U_cone * n[2]?

else:

result[0] = 0

And then, `u_total`

is defined as:

u_total = bempp.api.GridFunction(spaceU, fun=u_total_callable)

u_total.plot()

I’d appreciate any clarification on whether `U_cone`

should be included here.

Thank you!
