Time integration in comsol 3.5a

Please login with a confirmed email address before reporting spam

Hi everyone,

I am just wondering if there is a time integration function in comsol 3.5a. I am calculating fluid flow rate through a boundary and which is a function of time and I would like to integrate the flow rate with respect to time to get cumulative production. I am aware comsol 4 has the timeint function which I believe is what I am after but in comsol 3.5a instead. Does anybody have any idea?

Cheers,

Andres Bracho.

Hi Andres,
I am just wondering if you found how to do the integration. I m working on something similar.

Thank you

Hi Sanket,

Unfortunately I have not found out how to do time integration in 3.5a. At the moment I am trying to rebuild my model in the 4.2 version as I do not have much hopes of there being a similar function in the earlier versions.

Cheers,

Andres.
