Expression for concentration

I want to define in CFX an expression for concentration as a function of time: concentration decrease by 50% every second.

Anybody know how to define an expression?

More information needed:

Is this concentration at an inlet which gets convected away from there? Or is the concentration independant of the flow?

Please explain what you are trying to do.
