Hello dear members;
Im trying to simulate a water jet model in flow 3d v 10 but after 40 sec i face this message persistently;

recommend reducing cfpk by factor of 10


Although the process is not terminated, but the time step size is almost near to zero(elapsed time is getting longer and longer).
So is there anyway to resist time step size of being such small magnitude?
