With regards to the first paragraph, the timestep I had chosen was 0.0001 sec. I am a bit uncertain as to what you mean by "desired" frequency? I essentially chose a timestep to give me a courant...

Please see below for the results for lift and drag using the Realisable k-e model and the SST-k-w model. I find it strange that the k-e shows periodic behaviour whereas the sst-k-w does not seem to...

So essentially, in the case that the frequency of the turbulent events are higher than URANS is capable of capturing, then my results will most likely look strange? Many thanks for your help thus...

Hi Filipo The initial velocity field is obtained from running a steady state simulation for around 10000 iterations. The discretisation scheme used is first order implicit for time and second...

Replies: 8 Non-periodic Transient Behaviour? Views: 1,593 Posted By PedFr0 Non-periodic Transient Behaviour? Hi All I would like to know if it is possible, when using RANS based turbulence models, to achieve non-periodic yet transient behaviour. I am simulating flow over a heliostat model and have run...
