ANSYS CFX Adaptive Timestep

aeroman · July 23, 2009, 18:20

I am interested in a time accurate solution for a multiphase (air/water) problem, whereby it is important that the courant number fall below 1. This is easy enough to set up in CFX, however I have an expression for the flow velocity which is dependent on the value of the current timestep.

Sooo...My question is: What CEL expression (if any) can I use to call the current timestep into my equation, since it will be changing based on the adaptability criteria.

Any help help you can provide would be a huge help

Apollogies, I realize i should have put this in the CFX forum.
