Using Boundary Integration in an Expression

Please login with a confirmed email address before reporting spam

Hi,

I would like to know if it is possible to perform a boundary integration per simulation tick and use that information as part of an expression whose result would affect another boundary condition before the next simulation tick.

For example, I have a volumetric flow leaving a boundary, performing a boundary integration yields the volumetric flow. I would like to use that flow value in an expression to change the back-pressure of that boundary, per simulation tick.

I have only been able to perform a boundary integration in post processing. The alternative is to perform this task using the MATLAB interface, but I thought I would explore the possibility of a neater solution.

Many Thanks,

Regards,
Tom

you can define an integration coupling variable which will integrate the flow velocity over the boundary at each time step.
