Default length integral on a streamline

From a previous post, I understand that it should be possible to do a length integral on a streamline. Can someone suggest how to do the integration?

For example, I have a vairable A and another one t(which is water age), both calculated from a AV transport equation). How can get a length integral of A*t over a streamline?

Regards!

Hi,

In Post, create an expression defined as lengthInt(A*t)@Streamline

Thanks, Rui.

Actually I described my problem incorrectly in my previous post. Sorry.

I should calculate an integral of a parameter with time . Again for example, I know the distribution of A and water age t in the whole domain, what I need is the integral of A*dt or the distribution of accumulated A*t over the domain. How can I do this in post?

Best regards!

Gab
