How to visit P, U over a particular line in the domain?

xbchen168 · October 25, 2011, 00:26

Hi, I am new to OPENFOAM.

I want to update P, U, T, over a particular line inside the fluid domain, following a particular equation. I set the line as BAFFLE type. May I know how to update P, U, T over the BAFFLE after the fluid domain is solved? For example, T over the BAFFLE is a function of internal close cell P, U.

How to visit those internal cell U,P values around the BAFFLE cells?

Thanks for help.

a hint can be to define that particular line as thin wall! so you can apply those conditions as boundary condition with groovyBC utility !

look at here for groovyBC :
