Helmholtz equation in PDE module

Hi everyone, I have to use the Helmholtz equation of PDE module to analyze a 2D acoustic scattering problem: predicting the acoustic pressure field when a plane pressure wave incidents from the left side on a cylindrical shell. I compared the results obtained by using PDE module and acoustics module. However, they are different. In the PDE, on the left side boundary, I used 'Dirichlet Boundary Condition ' and set r=exp(i*k0*x); the rest boundaries, 'Zero Flux' was applied. Can anyone give me some tips about using PDE to analyze such a problem.
Thanks a lot!
