Defining Momentum Source Co-efficient using UDF
I've simulated the pressure drop in porous media using a UDF. The doubt which i am having is , in fluent the format of momentum source is
S = D*mu*Vj + C*0.5*rho*mod(v)*Vj
In UDF while defining source how will you define only viscous resistance(D) or only inertial resistance(C) as we are providing the source in general .
In need of some expert advice on thins issue
