length scale option
 

dear all,

i am a CFX user for the past 3 months and i have a doubt regarding the length scale option what we specify in the CFX-pre stage. i would be grateful if some body could explain me on "what is length scale option? why should we give that as "conservative/aggressive/value for length scale option"? is it necessary and compulsory that we should give that? how will it affect the results ?"

thank you friends

Hi,

This is discussed at length in the documentation. It is used to generate a psuedo-timestep for advancing the simulation in a steady state model.
