heisenmech is on a distinguished road
Hi all,

I've recently noticed something odd in Fluent. I plotted "Production of k" under Turbulence tab, and it was zero everywhere.

I created a custom field function for production of k as Fluent Theory Guided suggests for k-w SST ( Gk = mu_t*S*S ), as expected, it yielded realistic results.

However, I need to figure out why Fluent is plotting zero for Gk (I checked some other simulations, its all zero on them too).

Any help is much appreciated.
