    How did you specify the location of the microphone here using dolfinx?

      Hi Ekrem,

      You don’t sepcify the mic location in a modal analysis, you do that in the Modal Superposition (see related article).

      Anyway, after the modal participation computation you calculate the pressure field vector with the multiplication p = Φϕ. Then, you can project such vector in an empty dolfinx function:

      uh = Function(V)
      uh.vector[:] = p.array = “u”

      The rest is nearly identical to the case you find in the first article.
