I am missing some output files
 

I am missing some output files like epsilon and k in my time directories. Additional one of my species (the first) one is missing. All other output like p,U,T and all other species were sucessfully written into the time dir.

Does anyone has an idea or know how to track this strange behaviour?

Any ideas ?

Most propably you don't have t
 

Most propably you don't have turbulence enabled (or you're using a turbulence model that doesn't use k and epsilon). Which solver are you using?

Turbulence is enabled and I us
 

Turbulence is enabled and I use the RNG k-epsilon turbulence model. The solver is a user-coded one but I am do not aware that there is something which is related to my problem.

Try playing around with thw wr
 

Try playing around with thw writeOpt()-Method (inherited from IOobject) of the k and eps fields. My guess is that this was set from AUTO_WRITE to NO_WRITE somewhere ....
