Issue with incident wave in Transient Acoustics mode

Please login with a confirmed email address before reporting spam

Hi, I have to model a multilayer plate in water and get the reflected and transmitted waves through it, with a transient incident wave.

In the frequency mode, it's easy to put a background pressure field with a plane wave on one of the water medium, but in this case I would like to input a sine wave , time dependant

So I compute the whole study like this and, at the end when I plot the background pressure field, it shows just 0 through the whole time vector.

I thought it was an issue with how I defined my time step but I use a CFL of 0.2, with the sine frequency equals to 200Hz. My time vector ends at 1s. It really bothers me as no one around me is able to find the problem

Do you guys have any idea ? Thanks
