new intermittency function in CFX

alinik · April 17, 2015, 23:55

Hello everyone,

I need to change the definition of intermittency function in CFX and I do not know how.
I have to introduce a totally new intermittency function to CFX which is not already included in CFX library by default.

Any help is much appreciated.

Thanks,

alinik

Any idea where to begin?

It sounds like you need to use the "Specified Intermittency" option, and define a function which specifies intermittency over the whole domain. This function could be of any form, including an additional variable with convection/diffusion.
