Hi
I'm using the pressure acoustic, freqency domain node to modeling the standing plane wave in an inviscid fluid. Frequency is 1.5 MHz, the speed of sound in the fluid is 1500 m/s, wavelength is 1000 um and my incident wave direction is along the z axis, so my block dimensions are 500 * 500 * 500 in 3D. When my component is 3D, operating the standing plane wave just depends on the dimention along the z axis (direction of the incident wave), but when my component is 2D, operating the standing plane wave pedends the both directions x-axis and y-axis , and actually it is just operated when my cube dimensions are 1000*500 (direction of the incident wave in 2D is along the y-axis). Why does this happen in two dimensions?
Tkank you.
