I am writing a UDF that involves volume fraction for Unsteady RANS simulation with cavitation model turned on.

I define a user defined memory variable and use the following snippet of code to access it.

DEFINE_EXECUTE_AT_END(udf_name)
{
........ /* All the definitions */

d=Get_Domain(3); /* Vapor Phase domain

thread_loop_c(t,d)
{
begin_c_loop(c,t)
{
C_UDMI(c,t,1)=C_VOF(c,t);
}
}
end_c_loop(c,t)
}
}
(This is just to show how I access C_VOF.. I perform some other operations on it)

I get the value of C_UDMI(c,t,1) as 0 everywhere when the volume fraction of phase 2 varies from 0 to 0.4.

Can someone please help me on the same. Thanks
