Default Timescale
Posts: n/a
Hello CFX users,

I'm using energy equation with CFX, and I would like to know some precisions about its timescale. I know how the solver calculate it automaticaly. But as I want (and I need) to set it myself in order to accelerate the convergence, I have the following questions that I couldn't find answers in the help:

what does the timescale represents physically? how is it introduced in the energy equation? how the solver use it exactly? which connexion has it between the different iterations? If I increase it, the convergence is faster: so can I increase it hugely?

Thanks if you have some ideas, Juan

This is all discussed in the documentation. It also discusses the various methods of setting the time scales.

Lots of things are explain in the User manual. But I still don't understand how it is used by the equation?
