Module pressure 

Field pressure evaluation at exterior points

Computes the acoustic pressure field at evaluation points using the BEM representation formula:

p(x) = p_inc(x) + ∫_Γ [p(y) ∂G/∂n_y - (∂p/∂n)(y) G(x,y)] dS_y

For a rigid scatterer (Neumann BC), the normal velocity is zero, so the formula simplifies to:

p(x) = p_inc(x) + ∫_Γ p(y) ∂G/∂n_y dS_y
