could not find postporcessing option on vof with gamma-re theta turb. model

sail · August 12, 2011, 14:01

Dear all.

I'm running a URANSE vof simulation using the trasition - kosst model (gamma re-thehta).

the simulation works flawlessy, but i cannot postporcess the intermittency and momentum thickness in fluent. they do not appear in the drop down menu. it is also not possible to export those quantities in tecplot or anything similar. the model is on, the bl thickness or the skin friction coefficent are working (they are different from a simple ko-sst simulation) but i cannot plot the intermittency.

it is wierd, because my posptocessing works flawlessy if i use just a single phase simulation.

i'm using fluent v12.1

any idea would be greatly appreciated.

up! anybody with a newer version of fluent (13?) might want to give it a try on a rough test case? just 20k cells and 3 iteration would be great, just to see if i found a bug or a more weird problem...

as a future reference, if somebody should have the same problem and stumble on this thread:

Ansys support replied to my inquiry and it's officially a bug. v13 still doesn't have a fix at the time of writing.
