source term in a specific position

Hi, I'm working on laminar flow in a cylindrical pipe and I want to add uniform volume force as source term to pipe center not in all domain, how can i do that please? any help will be appreciated

any help please ???

One simple option is that you can implement the source into your equation and initialize using setFields

We have done this some time ago here

adding a constant volumetric source term to transport equation in a particular region

thank you for your reply, just a question, when I create a new field as source term, can I study the effect of this force on the velocity field?

I don't want to make new field, I want to add a force that affect on the velocity
