I need a help with correcting my result.
I am simulating the breathing crack effect and having a problem with the result.
The following is what I have simulated,
In order to create a thin crack, I used the debond command.
The results I got are shown below.
As you can see, the result is good when there is no crack. However, the result for the cracked one is weird, it almost looks like noise. I am not sure but I think it is because of the numerical dispersion. Do you have any suggestion in order to fix this problem?
