  Hi all,nDoes anyone know why FLUENT (k-wSST) yields zero for production of k everywhere in the fluid domain when plotting?nWhen I calculate tke production via CFF exactly the same way as Fluent (mu_t*S*S), it gives realistic non-zero results. nI've also checked my other simulations, production of k is zero regardless of simulation case in Fluent.nnAny idea why?.

  As an update, the issue seems to be persistent with other two equation models. Regardless of case, production of k yields zero. nI'm still desperately looking for an explanation, so if you have anything in mind, hit me up please!nnThanks.n

  Hello, nWhen you load the case, just run it for another iteration and then you should be able to see the right values. Production of k does not get stored in the dat file. n

  Ah Gosh, I've wasted my whole day trying to figure out this.nTHANK YOU VERY MUCH!n
