Hello,

I need to add source term to pisoFoam. Currently I'm doing it following way

fvVectorMatrix UEqn
(
fvm::ddt(U)
+ fvm::div(phi, U)
+ turbulence->divDevReff(U)
== ro.initForce(U,mesh,Fw)

);

ro.initForce(U,mesh,Fw) returns volVectorField

but I cannot see any signification change in my results. normally is this the way to add any source term to pisoFoam solver? Am I doing it right in Openfoam perspective?

further I'm using homogeneous dynSmagorinsky model as a LES model

Thanks in advance

i suggest, you should turn to "fvOption" source (in directory OpenFOAM-2.2.x/src ) to add source in to equations.

Dear song,

Thanks for ryour eply, I'm also thinking about this fvoption. what is the difference between adding explicit source term as in 1# and using fvoption. if you are familiar with fvoptions, please elaborate more information. it might enable faster implementation of code

Thanks

maybe you can refer to some tutorials.
use some search tools(software) , to see which tutorials have "fvOption" files in directory "system", then look into them carefully.

sorry, i am a new foamer, too, and this is all i can help you
