Deal all
I would like to ask some technical issues.
Assume that the PDE problem, where variable is called S.
when S(t=5)<=S(t=4), then save S(t=4) in a variable K. Again, if S(t=13)<=S(t=12), then save S(5=12) in that variable K. Therefore, K(1)=S(t=4) and K(2)=S(t=12).
The above problem is very easy adoped in MATLAB by using for circle and array [], but it seems that difficult adoped in COMSOL.
I would like to ask how to get the value in model setting so that it can be used in solving process.
