Hi all,

I would like to define a minimum timestep to start from in a simulation with auto timestepping. The timestep CFX estimates automatically, is too large......

Pascale,

Specify a "Physical Timescale" instead of using "Auto Timescale".

Yeah, you can play with your CEL. In CFX-5.6 there are some useful variables like citern(current timestep), aitern(accumulated timestep), etc...
Take a look on the "Variables Available for use in CEL Expressions" topic of the CFX-5 manual to know its definitions.
Be well, cfd guy
