one dimension ultrasound

Please login with a confirmed email address before reporting spam

I had a question about working with comsol on 1 dimension. I am trying to create a stream of water to PDMS to water again which I have done shown below. However, in the beginning water I want to have an ultrasound wave of 1MHz to be imputed (left to right) but I am having trouble with that. I have tried going to physics and adding a boundary but it doesn't work. I saw it work in a video on Youtube but that's because their model was 2 dimensional, in which they used the inlet feature however the inlet feature isn't in the one dimensional model. How would I solve this? or would it only be possible to do this if i use a 2 dimensional model?
