Circular variable dependency detected with prev() on COMSOL 5.3

Please login with a confirmed email address before reporting spam

Hello every body,

someone could tell me how to have a variable calculated with this same variable at the previous time step without the problem of "circular variable dependency " ?

Per example I want:

X = prev(X,1) + Y; with X and Y two variables.


Thank you in advance for your help.
