Gas phase velocity in DPM Drag UDF
 

Hello everyone.

I'm implementing an equation for particle drag. In order to call the carrier phase properties I'm using the following:

double C_p = c->sHeat;
double T_g = c->temp;
double Rho_g = c->rho;
double Mu = c->mu;
double U_g = ?

The names sHeat, rho, temp and mu are defined in the UDF user manual. However I want to define the u velocity of the carrier phase within the particle's cell. Does anyone know what this cell would be named as. Is there a list for these property names? Where can I get them from?

Cheers,

Hanz.
