How to reduce time step for Volume Fraction equati
 
In Eulerian-Eulerian multiphase simulation, the volume fractions are not converging. I want to reduce the time step size for the volume fraction equation only. The CFX manual says to modify it using CCL file. How to do that?

I know the following command to read and write the CCL file.

cfx5cmds -read (OR -write) -def <.def> -text <.ccl>

BUT where should I change the time step for volmume fraction equations.

Thanks, Kushagra
