Dear all,

I am using UDFs to impose a constant omega value at the interface as a boundary condition of my two phase stratified channel flow.

I am also using periodic boundary conditions so there is no way to hook a DEFINE_PROFILE UDF.

I have tried using DEFINE_SOURCE it adds a source variable to every grid cell.

Can anyone suggest some way to bypass this.

Below is the UDF SOURCE code

#include "udf.h"

#define C1 2927

DEFINE_SOURCE(omega_source, c, t, dS, eqn)
{
    real x[ND_ND];
    real y;
    real source;
    real abcd;
    C_CENTROID(x, c, t);
    if (1.5<C_R(c,t)<900)
        source = C1;
    dS[eqn] = 0;
    return source;
}
