Hello, I´m a new user at Comsol and still learning so all the help you guys can give me it will be welcomed.
I´m having issues when trying to make a graph line or table with the y axis being the time a certain variable reaches the value 1.
I tried to simply make a point evaluation on the geometry with the expression: t=u1>1 to make me return that values on a table but it says that i have a sintax error and i get the same when i try to make a line graph. Is there anyway easy i can do what i want?
- Expression: t=u1>1
- Subexpression: =u1>1
Position: 3
Best regards, and thank you for you help.

Hi Fernando,
In Comsol, if statements are given by inequalities. So in your case, when you have the expression u1>1, this will be equal to 1 when the inequality is true, and 0 when it is not. Therefore, if you have t*(u1>1), this will be equal to t if the inequality is true, and 0 if it is not. Does that andwer your question?
Cheers,
Alex
