I am new to COMSOL. I am currently working on UCA modeling but I have this issue.
I have this model in which there are 3 domains.
1 elastic shell(200nm thick 2micron radius)
2 air inside the shell
3 water which has 1and 2 inside(10 micron radius)
B.C
point source at center (0,0,0)
spherical wave radiation on domain3
I was able to plot 1d point graph and find its natural frequncy by frequency sweep using frequency domain just like the way this paper shows
www.comsol.com/papers/2523/
for next step I'd like to plot radius and other quantities (e.g., pressure) vs. time for constant frequency and amplitude of the acoustic forcing using 1d point graph
but when I choose time domain I cannot seem to find power source that apply a constant sinusoidal wave to the model.
Thank you in advance.
