How to visually observe point of singularities in the post processing step

Please login with a confirmed email address before reporting spam

Hi All, This is a follow up to my previous post here

I have tried to define point sinks in the geometry. From what I understand the positions at which the point sinks are defined will act as point of singularity since the solution will tend toward infinity. Please correct me if I am wrong. However, I am not able to observe this in the results - concentration vs. plot that is generated.

I would like to know how this can be visually observed. result.

I expect that the solution curve will dip to infinity and one would observe sharp peaks (like shown in the gif attached in this post www.comsol.co.in/forum/thread/130441/wave-equation-singularities-at-the-source-point). But I am not sure why this isn't observed in my solution curves.

Suggestions will be really helpful.
