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

Re: Timescale

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

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

All times are GMT -4. The time now is 11:10.
