Hi, In a "Pressure Acoustics, Frequency Domain" problem, I defined a boundary condition of type "Plane Wave Radiation" and added "Incident Pressure Field" to it (normal vector was perpendicular to surface). In the reults, pressure on this surface was not uniform. Is this behaviour correct? To my knowledge, pressure on a plane wave surface is uniform and varies with time (not position on surface)!

Hi Jaber
To visualize the incident pessure you need to plot the variable acpr.p_i, if what you plot is say the total pressire acpr.p_t you may see variations over the surface as this variable also contains the reflected pressure. If on the other hand you are applying the conditon on a non-flat surface you will see variations in acpr.p_i as the plane wave expression depends on position (x,y,z) in your model.
